----------------------------------------
Summary: 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
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.
