Timeout exception while IndexSearch on not valid column values
--------------------------------------------------------------
Key: CASSANDRA-3630
URL: https://issues.apache.org/jira/browse/CASSANDRA-3630
Project: Cassandra
Issue Type: Bug
Affects Versions: 0.7.0
Reporter: Evgeny Ryabitskiy
Fix For: 1.0.6
While index_scan it is possible that column value is not valid. For example if
it is a DynamicCompositeType there can be stored LongType and search is using
DecimalType. In result cassandra has following behavior:
1) Cassandra server logs Fatal exception and stops MessageDeliveryTask
execution without any response to client
2) Client wait response until timeout, at result application fails with
TimeoutException
I think this behavior is incorrect, and client should get reply about search
request failure.
