Benjamin Lerer commented on CASSANDRA-9527:
-------------------------------------------
The issue is valid.
Our test is:
{code}
if ((cfm.getCfDef().isCompact || !cfm.getCfDef().isComposite) && cd.type !=
ColumnDefinition.Type.REGULAR)
throw new InvalidRequestException("Secondary indexes are not
supported on PRIMARY KEY columns in COMPACT STORAGE tables");
{code}
The problem is that the type of the c column is
{{ColumnDefinition.Type.COMPACT_VALUE}} and not
{{ColumnDefinition.Type.REGULAR}}.
> Cannot create secondary index on a table WITH COMPACT STORAGE

> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: cassandra v2.0.13
> Reporter: fuggy_yama

> Priority: Minor
> Fix For: 2.0.x

>
> In CASSANDRA-8156 it is said that secondary indexes are not allowed on
> clustering columns in COMPACT tables.
> However, I found that it is not possible to create a secondary index on the
> value column in a COMPACT table:
> CREATE TABLE t (
> a INT,
> b INT,
> c INT,
> PRIMARY KEY (a, b)
> ) WITH COMPACT STORAGE;
> CREATE INDEX ON t (c);
> *Bad Request: Secondary indexes are not supported on PRIMARY KEY columns in
> COMPACT STORAGE tables*
