Jan Chochol created CASSANDRA-6607:
--------------------------------------

             Summary: Unable to prepare statement with batch and delete from collection
                 Key: CASSANDRA-6607
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6607
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Jan Chochol
            Priority: Minor


It is not possible to prepare statement with batch containing delete operation on one item of collection, e.g.:
{noformat}
BEGIN BATCH
DELETE colection[?] FROM table WHERE key = ?;
APPLY BATCH
{noformat}
Result of preparing such statement is:
{noformat}
java.lang.ArrayStoreException: org.apache.cassandra.cql3.ColumnSpecification
{noformat}
With stacktrace:
{noformat}
ERROR 16:26:36,816 Unexpected exception during request

{noformat}

This fix seems to help:

     }
{noformat}

It is probably corrected in Cassandra 2.0 by commit {{e431fb722f80d8957a0a7fd2ecf80333e9275c53}} (CASSANDRA-5443).
We  are facing this issue with Cassandra version 1.2.11.
Would it be possible to fix this issue in branch 1.2?
