> CQL schema generated by DESCRIBE KEYSPACE fails to import with custom indexes
> -----------------------------------------------------------------------------
>
> Key: CASSANDRA-16482
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16482
> Project: Cassandra
> Issue Type: Bug
> Components: CQL/Syntax
> Reporter: Mike Adamson
> Assignee: Benjamin Lerer
> Priority: Normal
> Fix For: 4.0-rc1, 4.0
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The CQL schema generated by a DESCRIBE KEYSPACE on a keyspace with a table
> that contains a custom index cannot be reimported.
> The reimport of the schema fails with:
> {noformat}
> InvalidRequest: Error from server: code=2200 [Invalid query] message="Cannot
> specify class_name as a CUSTOM option"
> {noformat}
> The reason for this is that the custom index definition is created with
> {{class_name}} and {{target}} options added to it in it's {{WITH OPTIONS}}
> section. This is then picked up by the {{IndexAttributes.validate}} method
> that specifically rejects them.
> Note: This only seems to happen if the custom index was created with options
> in the first place. So if the {{CREATE CUSTOM INDEX}} statement didn't
> originally have a {{WITH OPTIONS}} section then it won't have the
> {{class_name}} and {{target}} options added to it.
> h3. Steps to reproduce
> {noformat}
> CREATE KEYSPACE test WITH replication = {'class': 'SimpleStrategy',
> 'replication_factor': '1'};
> CREATE TABLE test.test (id int PRIMARY KEY, value text);
> CREATE CUSTOM INDEX ON test.test(value) USING
> 'org.apache.cassandra.index.sasi.SASIIndex' WITH OPTIONS = {'is_literal':
> 'false'};
> DESCRIBE KEYSPACE test;
> {noformat}
> Trying to import the resultant schema will fail.
