[jira] [Created] (CASSANDRA-4489) LCS with Composite Columns NPE

Wing Lian created CASSANDRA-4489:
------------------------------------

             Summary: LCS with Composite Columns NPE
                 Key: CASSANDRA-4489
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4489
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.1.2
         Environment: Mac OS X 10.8 

java version "1.6.0_33"
Java(TM) SE Runtime Environment (build 1.6.0_33-b03-424-11M3720)
Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03-424, mixed mode)

            Reporter: Wing Lian


Creating the CF in cqlsh -3
cqlsh> CREATE KEYSPACE tt WITH strategy_class=SimpleStrategy AND strategy_options:replication_factor=1;
cqlsh> USE tt;
cqlsh:tt> CREATE TABLE breakable (
      ...   dt timestamp,
      ...   id timeuuid,
      ...   metadata text,
      ...   PRIMARY KEY (dt, id)
      ... );
cqlsh:tt> 

Then changing to LCS using the CLI
[default@unknown] use tt;
Authenticated to keyspace: tt
[default@tt] update column family breakable with compaction_strategy=LeveledCompactionStrategy;
org.apache.thrift.transport.TTransportException

And then trying to view the table schema
cqlsh:tt> describe table breakable;

'NoneType' object has no attribute 'startswith'
cqlsh:tt> 

Restarting cassandra causes an NPE

[jira] [Updated] (CASSANDRA-4489) LCS with Composite Columns NPE

Posted by "Pavel Yaskevich (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/CASSANDRA-4489?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Pavel Yaskevich updated CASSANDRA-4489:
---------------------------------------

    Attachment: CASSANDRA-4489.patch

That happens because CQL3 has metadata that is not exposed through thrift CfDef API so when CLI is used to update ColumnFamily defined/used by CQL3 it would be missing such metadata, I'm attaching a patch to fix that but I think if one wants to use CQL3 one better stick with it for all operations.
