Hi,
I'd like to install OpsCenter 3.2 on Red Hat Enterprise Linux Server release 5.8 (Tikanga), which currently has Python 2.4.3.
I see from the docs that Python 2.6+ is required. What's the latest version that's supported 2.7 or 3.3?

Hi all,

I like Cassandra, I use it for all of my projects, it's great! However, I observe that C* is continuously moving to become equivalent in terms of data modeling to SQL-world....

If I understand correctly with CQL3 one can no longer have dynamic column names. All column names should be precisely defined with its name and type.

What I really(!) like in C* is schemaless. Should I worry that some day C* will drop completely support for schemaless data models? I just don't want to work in XxxSql world again :) What are the (super)long term plans for C*?

More technically: I need to have one CF for storing thousands of different tabular data (files). Almost each file with tabular data have different set of column names (with different types: double, long...). I simply cannot have thousands of different CFs, it would be not optimal. So I need to have one schemaless CF :( Should I be worry that my dreamy database will vanish?

Thanks for answers!

hi,

I am not clear on how to calculate data sizing ; the documentation
(http://www.datastax.com/docs/1.2/cluster_architecture/cluster_planning) states:
"On average, raw data is about two times larger on disk after it is loaded into the database, but could be much smaller or larger depending on the characteristics of your data and tables. " .
Well, what about compression ? It seems like this is not taken into account at all - this other link:
http://www.datastax.com/docs/1.2/operations/compaction_compression#compaction-compression
states "2-4x reduction in size" with compression on.

My question is: does the cluster planning documentation (first link) take into account compression (second link) by default or not ??
Documentation probably needs to be updated.

Thanks,
Matt

hi,

The documentation says (http://www.datastax.com/docs/opscenter/online_help/backups/data_backups) that OpsCenter can manage backups and restores from snapshots.
How about managing incremental backups , can Opscenter do this also ?
Otherwise, how to manage full + incremental backups/restores from OpsCenter ? I am hoping one doesnt have to do full backup/restores from Opscenter and manual scripting for incrementals ..

cheers,
Matt

First off this functionality works fine in the Datastax 2.0 version but no longer appears to work in 3.0. Basically when I add a copyFIeld value to the SOLR schema from a string it throws the exception listed below. If I remove the copyField the error goes away, and if I use the cli to insert a value in and view it everything works as expected. When using Hector, SolrJ or the SOLR admin UI I get an exception. I've included and example schema as well as the exception. I can add values fine thorugh the cli but when trying to view them through the UI or when adding them through the hector API I get the exception listed below.

I also verified when I switch back to version 2.x everything works fine with the same schema, column family definitions, etc.... It would be nice if attachments were also supported the uploading of config files etc... would be easier than copy and pasting them.

We recently split our 6-node solr datacenter into a no-Solr Cassandra datacenter and a Solr datacenter (dse delegate snitch). I'm noticing high load on one of the nodes in the Cassandra DC and according to OpsCenter, it's rebuilding the secondary index.

The only secondary index should be Solr indexes which I wouldn't think it should be rebuilding. Should it?

Does something need to be done to scrub the secondary indexes or is this expected behavior?

Hi,

I am trying to build a cluster with 4 nodes.
For the node on which the opscenterd runs the installation fails with the message :

Install Errored: Unable to create yum repo file: /tmp/datastax4089829439812535937.repo

Error Details
Install Errored: Unable to create yum repo file: /tmp/datastax4089829439812535937.repo exit status: 1 stderr: sudo: sorry, you must have a tty to run sudo

How can I correct this issue?

Regards Hans-Peter

Hi,

We have setup a single node cluster of DSE 3.0 Cassandra with Kerberos authentication.
Setup details are :-

i) Kerberos server (Ubuntu 12.0.4 32 bit)
ii) DSE Cassandra Node (Ubuntu 12.0.4 32 bit) , although 64 bit machine also didnt make any difference!

We can restart DSE cluster successfuly, and can connect to it via CQLSH client as well.

Now, from a separate machine (ubuntu 12.0.4 64 bit/32 bit), we are trying to connect this Cassandra node using a java client (Hector API) and getting exceptions(given at the last of this post).

Please help us!

Hi all,

After upgrading dse, i have an error :
Caused by: org.apache.solr.common.SolrException: Plugin init failure for [schema.xml] fieldType "string_contains": Plugin init failure for [schema.xml] analyzer/filter: Error instantiating class: 'org.apache.lucene.analysis.ngram.NGramFilterFactory'

I correct my sorl schema and post it, but it still failed with the same error. How can i force it to
use the new schema.

Thanks,

Hello,

A C* user and I have posted some issues we have met on the new 3.2 OpsCenter.

Could you please check those issues and tell us if they are bugs or if we missed something ?

http://grokbase.com/t/cassandra/user/137yvywerr/two-problems-about-opscenter-3-2

You can answer here, I will post a link to this topic on the ML.

I have a 2 node single data center. I am using the csharp driver. When we had it 1 node 1 DC it was fast. now that we have expanded it to a 2nd node it works but it is very slow responding.
_cluster = Cluster.Builder()
.AddContactPoints("connection1",""connection2")
.WithCredentials("user", "********")

.Build();

// _cluster = Cluster.Builder().AddContactPoint("connection1","connection2")
//.WithCredentials("user","*******")
//.WithoutRowSetBuffering().Build();

_session = _cluster.Connect("SE");

return _session;

anyone else experiencing this issue?

Hello, we have a fresh installation of dse-full 3.1.1-1. We've enabled
- authenticator: org.apache.cassandra.auth.PasswordAuthenticator
- authorizer: org.apache.cassandra.auth.CassandraAuthorizer

We've commented out auth_replication_strategy and auth_replication_options, replication_factor config settings because the comments in the config file around these parames told us to do so.

However, we've changed the system_auth keyspace replication options to look like this:
strategy_class: org.apache.cassandra.locator.NetworkTopologyStrategy
strategy_options: {"DC1":"2", "DC2":"2"}

Then we ran nodetool repair on all of the nodes.

With this setup, we are able to use cqlsh -3 ip 9160 -u cassandra -p cassandra, it works well. However, when we want to use the native transport with port 9042 (start_native_transport is true in the config, we haven't touched that) from a client computer using a c# lib located here: https://github.com/pchalamet/cassandra-sharp/tree/master/cqlplus, it just does not work.

If we disable authentication to use AllowAll for both authorizer and authenticator, it is working again.

This was working with an earlier version using native debian packages, not the dse (ie, deb http://www.apache.org/dist/cassandra/debian 12x main).

Hi,
I would like to know if Datastax can implement either SAML 2.0 protocol or the WS-Federation passive requester profile protocol.

Thanks.

Hi,

I've been trying to run DSE Cassandra with Kerberos authentication enabled but with no luck so far.

I have enabled kerberos authentication in the Cassandra.yaml file and used the following values in dse.yaml:

keytab: /root/dse.keytab
service_principal: dse/_HOST@REALM
HTTP_principal: HTTP/_HOST@REALM
qop: auth

Now everytime I start cassandra server using "dse cassandra -f" I see the following errors:

ERROR 14:47:44,888 An error occurred during transport negotiation
com.datastax.bdp.transport.common.TTransportNegotiationException: Improper authentication type requested. Requested auth: No authentication with service principal: FRAMED_TRANSPORT_FAKE_PRINCIPAL, Allowed auth: Kerberos

at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)
at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

I have added dse as a service principal on the dse.keytab and using "klist -k dse.keytab" confirms this:

dse/10.14.101.27@EVENG.LOCAL
dse/10.14.101.27@EVENG.LOCAL
dse/CassENT.eveng.local@EVENG.LOCAL
dse/CassENT.eveng.local@EVENG.LOCAL

Could someone please provide pointers to why I'm seeing those errors?

Thanks

We are using DataStax Enterprise trial. A system which was working nicely started to intermittently stop working / get timeout exceptions. This has gone on for several days without resolving itself.

Stack Trace:

Exception:
me.prettyprint.hector.api.exceptions.HTimedOutException: TimedOutException()
at me.prettyprint.cassandra.service.ExceptionsTranslatorImpl.translate(ExceptionsTranslatorImpl.java:42)
at me.prettyprint.cassandra.connection.HConnectionManager.operateWithFailover(HConnectionManager.java:260)
at me.prettyprint.cassandra.model.ExecutingKeyspace.doExecuteOperation(ExecutingKeyspace.java:113)
at me.prettyprint.cassandra.model.MutatorImpl.execute(MutatorImpl.java:243)

I read that a timeout is sometimes a "in progress" exception so i planned to trace my query and see if it was slow, however after restarting a single node in the cluster it started working again perfectly so it does not look like it was related to my query.

If a single node was providing timeouts shouldn't the forwarding nodes stop sending requests to that box? The replication factor was set to 1 so maybe they had no alternative?

There are some messages in the node logs:

I get this a lot:
HintedHandOffManager.java (line 374) Timed out replaying hints to /10.33.175.144; aborting further deliveries

And this:

Any ideas?

Any ideas.

Just curious what version of Cassandra its based on? 1.2.3 or latest still?
Since it supports Binary Protocol, I'm excited and like to give it a go soon!!
Cassandra 2.0.0-beta2 was released on 2013-07-25 and I suppose this is not the version.

This is in reference to my earlier question raised in this forum @ http://www.datastax.com/support-forums/topic/cql-binary-protocol-support-missing-in-datastax-enterprise-301#post-9502

Hi,

I am evaluating DSE Enterprise and now have everything connected, Opscenter and Cassandra are running on a single node. The Agent is connected to Opscenter and everything looks good...

except...

When i click the Data Backups menu option i am presented with the following error.

Error loading snapshots: [node 172.17.1.158] Unable to add group permissions to /var/lib/cassandra/data and its subdirectories, and the current permissions do not allow the agent to examine the snapshot files.
exit status: 1

stderr:
sudo: a password is required
(172.17.1.158)

I have been through all the documentation and cannot find a mention on where to configure any authentication for the backups.

I am not sure if this something has gone wrong with the permissions because i emptied the data folder at the start of the install as per the installation instructions for DSE...

If anyone can assist i would greatly appreciate it.

Thanks
Paul
