bibintjohn1 on "0 of 1 agents connected : Unable to connect to Node"

Hi,
I am new to Cassandra. when i tried to explore using Opscenter is it showing me " 0 of 1 agents connected".
Upon trying to configure, it is asking for below details.

Enter SSH credentials to connect to your nodes. The user must have root or sudo privileges (a sudo password can be entered in the "password" field). The information you enter is not saved or stored.

Unable to SSH to some of the hosts

Unable to SSH to 127.0.0.1:
global name 'get_output' is not defined

If you need to make changes, you can press "Retry" and the installations will be retried.

so what user and password should i use here?

Appreciate your help.

Hello,

when I create new table with cassandraemon in C#.NET code, the table is created. I can also launch OpsCenter. I can see my table in "schema" tab. However, when I click on its name, I get the eror:

Error loading column family: Make sure all agents are running and connected properly.

I find this error a little bit uninformative. What exactly should I run? Is there any documentation about this error?

This is not a big problem, as I may try to use CQL language in Cassandra CLI Utility to check if I have added new data correctly to my table. However, that would be easier to do it with OpsCenter.

Best regards!

PS

[default@MyKeyspace] SELECT * FROM MyTable;
Syntax error at position 7: unexpected "*" for SELECT * FROM MyTable;.

Hi Forum,

For some time i was looking for CASE QUERY support in pig, and recently they have started supporting it (https://issues.apache.org/jira/browse/PIG-3268). Well now just want to know by what time DSE will be going to use that version of pig, as we are using DSE solution in our product.

Hi,

If I have a Cassandra ColumnFamily and I try to create a Solr schema for this column family it won't work if any of the columns has data type other than utf8. If all are utf8 then there are no problems. If there's no CF and I post the schema with fields containing other than utf8 (string) it works w/o problems, creating the corresponding Cf columns with the correct data types. The only problem is when I try to map an existing column family.
The error is also a bit strange:
Caused by: javax.xml.parsers.ParserConfigurationException: Current validation_class and found SolrType do not much for column column_name

I have declared all the fieldTypes correctly (as I said, it workd if there's no column family previously declared).

Any idea?

Thank you,

Cristian

I had Datastax DSE 2.2 with Solr, in which i ran the Wikipedia demo. Everything worked fine. I then upgraded to DSE 3.0, and rebuilt the Solr index. Now everytime i hit the URL :

http://myserverURL:8983/solr/wiki.solr/admin/
I get a 404 'The requested resource (/solr/wiki.solr/admin/) is not available.' from Tomcat.

I looked in /var/log/cassandra/system.log and there is no error. I found this resource: http://www.datastax.com/docs/datastax_enterprise3.0/upgrade/solr_upgrade I ran the scripts in there; everything again runs fine for me, but doesnt solve my error. Any idea ? Have the resource file locations for Tomcat have moved in DSE 3.0 ?

Cheers, Matt

Hi i tried setting up a four node cluster to create a Cassandra developmental environment on linux machine with CentOS 6.3 distribution. The version for the cassandra is "cassandra12-1.2.3-1.noarch" with the following DataStax package "dsc12-1.2.3-1.noarch". Cluster setup was successful with all nodes functional, you can see the details here :

After the succesfull installtion of cassandra cluster i tried installing Opscenter with the following version
opscenter-free-3.0.2-1.noarch. For the installation i edited the opscenter.conf, the installation worked fine but when i tried to install opscenter agents on each cluster machine it showed the following error :
"Agent installtion failed". For the installation i followed the process of providing username and password which has sudo privelages and accepted the generated fingerprint after which i got this error.

Please suggest me the probable cause of the installation failure of opsceneter agents , please note i am working in an organization where there are few restrictions, one of them is "restricted proxy". I have checked the log in /var/log/opscenter/opscenterd.log which i'm pasting it here for reference :

Now that the Solr documentation is correctly updated to show that ngroups and facets are not supported across a sharded environment, how will Datastax respond? My understanding is DSE uses Cassandra's random partitioner which means that it is impossible to shard your data such that all query results will reside in a single shard. This means that all field collapsing features of Solr are not available in a Datastax Enterprise environment.

Hi,

I am unable to chose the release from the Datastax AWS AMI : ami-b2212dc6

Cluster started with these options:
--clustername Extend --totalnodes 3 --version community --opscenter no --release 1.2.2

[...]

------------------------------------
DataStax AMI for DataStax Enterprise
and DataStax Community
AMI version 2.4
DataStax Community version 1.2.3-1

------------------------------------

It looks like "--release 1.2.2" is ignored.

Is there a way with cqlsh or with the Solr http api to remove all rows/documents in a given column family (or entire keyspace) that are older than a given timestamp? If so, what is the recommended way to do it?

I've been wrestling with the CQL syntax in cqlsh for hours and am giving up. From the "help" for the DELETE command, I see that there's a "USING TIMESTAMP" option, but for the life of me I can't figure out how to actually use it. Extensive searching has brought up little more than is given in the help.

All I've found indicates that there should be some way to use it in this form:
"DELETE ... USING TIMESTAMP <timestamp>;"
I've tried
"DELETE * from <cf_name> USING TIMESTAMP <timestamp>;"
but I get a cryptic "expecting K_WHERE" message. So I try
"DELETE * from <cf_name> USING TIMESTAMP <timestamp> WHERE key='<value>';"
just to see if I can get something to work, but then I just get the equally helpful message
"extraneous input '*' expecting K_FROM"

Any ideas?

The release doc of dse 3.0.1 says it depends on solr 4.0.2. I tried to find the 4.0.2 version jars of solrcore and solrj, but it seems that they are not hosted on the solr site. Could someone please give me a pointer on how to find the solrj library that fits dse 3.0.1? Thanks!

I am trying to upgrade to dse3.0.1 with solr. On my dev machine, I am able to start dse3.0.1 and perform indexing on Solr. However, when I keeps on having issue with stopping dse. From the log, seems like it always hangs at the following stage:

Hi,

I am looking for functionality in pig script "parameter substitution in script including white space character". But some how was not able to do that, though from pig JIRA issues, it can be said that they are supporting it since 0.9 series. To investigate further i posted the question in pig user group as well as in stack overflow (http://stackoverflow.com/questions/16229364/whitespace-character-in-case-of-parameter-substitution). According to one of the user in SO, it might be a problem with DSE distribution. So basically want to confirm whether if it is problem related pig packaging or something else. And yes i am using DSE3.0 i.e pig 0.9.2

Hi,

I have created few schema's and uploaded into DSE-Solr. In one of the schema I have used TrieIntField for integer field and it seems at present its not supported.

Now the system got shutdown for some reason and I tried to restart DSE using the command
./dse cassandra -s

But the DSE is not starting due to an exception in one of the schema (contains a field of type TrieIntField). If one of the schema's is not proper it has to continue with other schema's and the DSE server should be started. But at present the server itself is not starting due to this error.
Is this expected?
Then how to delete that particular schema which is causing issue.

Please find below the full details of the exception I am getting:

Hi

Please help me to find where can I download or how can I use the following:

1. sample database/dataset according to this guide: http://www.datastax.com/docs/1.1/dml/using_cli#creating-a-keyspace

2. or other advanced developer guide which can produce a nice example(s) of Cassandra key features. It can be detailed
code of loading big dataset (include it) and query/analyze it real time.

3. I'll be happy to know about any other options for a Cassandra demo project.

Thank you

Hi,

I want to do a migration of AMI-based C* cluster from DSE 2.2 to DSE 3.0.
Before performing it on a production environment, I want to check it on a test env.

Is there a way to get previous versions of "DataStax Auto-Clustering AMI"? Ubuntu 10.10 based preferably.
As I can see from AWS console, only the latest (based on Ubuntu 12.04) is available.

And (just in case): yep, I know about option to install previous DSE version thru "--release <ver>" AMI start user param. But that will be still new AMI Ubuntu 12-based instance with old DSE. :)

Best regards,
Dmitry Ivanov.
