Philip Thompson commented on CASSANDRA-8786:
--------------------------------------------
Seems like an upgrade issue on tables created via thrift then.
> NullPointerException in ColumnDefinition.hasIndexOption
> -------------------------------------------------------

> Key: CASSANDRA-8786
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8786
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: Cassandra 2.1.2
> Reporter: Mathijs Vogelzang
> Assignee: Aleksey Yeschenko
> Fix For: 2.1.4
>
>
> We have a Cassandra cluster that we've been using through many upgrades, and
> thus most of our column families have originally been created by Thrift. We
> are on Cassandra 2.1.2 now.
> We've now ported most of our code to use CQL, and our code occasionally tries
> to recreate tables with "IF NOT EXISTS" to work properly on development /
> testing environments.
> When we issue the CQL statement "CREATE INDEX IF NOT EXISTS index ON
> "tableName" (accountId)" (this index does exist on that table already), we
> get a {{DriverInternalError: An unexpected error occurred server side on
> cass_host/xx.xxx.xxx.xxx:9042: java.lang.NullPointerException}}
> The error on the server is:
> {noformat}
> java.lang.NullPointerException: null
> at
> org.apache.cassandra.config.ColumnDefinition.hasIndexOption(ColumnDefinition.java:489)
> ~[apache-cassandra-2.1.2.jar:2.1.2]
> at
> org.apache.cassandra.cql3.statements.CreateIndexStatement.validate(CreateIndexStatement.java:87)

> {noformat}
> This happens every time we run this CQL statement. We've tried to reproduce
> it in a test cassandra cluster by creating the table according to the exact
> "DESCRIBE TABLE" specification, but then this NullPointerException doesn't
> happon upon the CREATE INDEX one. So it seems that the tables on our
> production cluster (that were originally created through thrift) are still
> subtly different schema-wise then a freshly created table according to the
> same creation statement.
