Unable to create a keyspace

I have a 3 node Cassandra 2.1.0 cluster and I am using datastax 2.1.4 driver to create a keyspace followed by creating a column family within that keyspace from my unit test.

But I do not see the keyspace getting created and the code for creating column family fails because it cannot find the keyspace. I see the following in the system.log file:

INFO  [SharedPool-Worker-1] 2015-01-28 17:59:08,472 MigrationManager.java:229 - Create new Keyspace: KSMetaData{name=testmaxcolumnskeyspace, strategyClass=SimpleStrategy, strategyOptions={replication_factor=1}, cfMetaData={}, durableWrites=true, userTypes=org.apache.cassandra.config.UTMetaData@370ad1d3}

This issue doesn’t happen always. My test runs fine sometimes but once it gets into this state, it remains there for a while and I can constantly reproduce this.

Also, when this issue happens for the first time, I also see the following error message in system.log file:

Anyone has any idea what might be going on here?

Thanks Carlos for pointing that out. The clock on one of the nodes was not in sync and fixing that solved the issue.

Saurabh;

a)   How exactly are the three nodes hosted.
b)  Can you take down node 2 and  create the keyspace from node 1
c) Can you take down node 1 and  create the keyspace from node2
d)   Do the nodes see each other with 'nodetool status'

cheers

Re: Unable to create a keyspace

I repeat the test after verifying that the keyspace has been dropped.

Also, I do not want any replication as of now that’s why replication factor is 1. But I don’t think that should be the reason for the command not propagating to other nodes.

One more thing that I observed right now is that if I create the keyspace from node 1 and node 2, it doesn’t get created but if I try to create it from node 3, it does get created. Node1 and Node 2 are Vms hosted on the same physical hardware, not sure if that has anything to do.

Thanks,
Saurabh

Saurabh a vague suggestion when you are dropping can you wait for sometime to let the change propagate to other node.Also I see a replication factor 1 but you have 3 nodes....

Thanks Adam. I upgraded to 2.1.2 but still seeing this issue. Let me go in a bit more detail as to what I am seeing – When I create a keyspace for the first time in a 3 node cluster, it works fine but if I drop the keyspace and try to recreate it, I see that the node received the request to create it but it didn’t delegate the request to other nodes because of which the keyspace didn’t get created on other two nodes.

But the request for creating a table does get propagated to other nodes and since they can’t find that keyspace they throw an exception.

I have 2 nodes as seeds, so the seeds property in cassandra.yaml for all 3 nodes looks like – seeds: "<node1ip>,<node3ip>"

Following is that I see in system.log file when I enable DEBUG mode:

Subject: Re: Unable to create a keyspace

I would first ask if you could upgrade to the latest version of Cassandra 2.1.x (presently 2.1.2).

If the issue still occurs consistently, it would be interesting to turn up logging on the client side and see if something is causing the client to disconnect during the metadata refresh following the schema change. If this yields further information, please raise the issue on the driver's user mailing list.

I have a 3 node Cassandra 2.1.0 cluster and I am using datastax 2.1.4 driver to create a keyspace followed by creating a column family within that keyspace from my unit test.

But I do not see the keyspace getting created and the code for creating column family fails because it cannot find the keyspace. I see the following in the system.log file:

This issue doesn’t happen always. My test runs fine sometimes but once it gets into this state, it remains there for a while and I can constantly reproduce this.

Also, when this issue happens for the first time, I also see the following error message in system.log file:

Re: Unable to create a keyspace

Posted by Asit KAUSHIK <as...@gmail.com>.
Saurabh a vague suggestion when you are dropping can you wait for sometime
to let the change propagate to other node.Also I see a replication factor 1
but you have 3 nodes....

Re: Unable to create a keyspace

Posted by Saurabh Sethi <Sa...@symantec.com>.
Thanks Adam. I upgraded to 2.1.2 but still seeing this issue. Let me go in a bit more detail as to what I am seeing – When I create a keyspace for the first time in a 3 node cluster, it works fine but if I drop the keyspace and try to recreate it, I see that the node received the request to create it but it didn’t delegate the request to other nodes because of which the keyspace didn’t get created on other two nodes.

But the request for creating a table does get propagated to other nodes and since they can’t find that keyspace they throw an exception.

I have 2 nodes as seeds, so the seeds property in cassandra.yaml for all 3 nodes looks like – seeds: "<node1ip>,<node3ip>"

Following is that I see in system.log file when I enable DEBUG mode:

Subject: Re: Unable to create a keyspace

I would first ask if you could upgrade to the latest version of Cassandra 2.1.x (presently 2.1.2).

If the issue still occurs consistently, it would be interesting to turn up logging on the client side and see if something is causing the client to disconnect during the metadata refresh following the schema change. If this yields further information, please raise the issue on the driver's user mailing list.

I have a 3 node Cassandra 2.1.0 cluster and I am using datastax 2.1.4 driver to create a keyspace followed by creating a column family within that keyspace from my unit test.

But I do not see the keyspace getting created and the code for creating column family fails because it cannot find the keyspace. I see the following in the system.log file:

This issue doesn’t happen always. My test runs fine sometimes but once it gets into this state, it remains there for a while and I can constantly reproduce this.

Also, when this issue happens for the first time, I also see the following error message in system.log file:
