Internal error processing get_columns_since
-------------------------------------------
Key: CASSANDRA-136
URL: https://issues.apache.org/jira/browse/CASSANDRA-136
Project: Cassandra
Issue Type: Bug
Affects Versions: trunk
Environment: Hudson build #59, accessing Cassandra via thrift/python
Reporter: daishi
In a cluster configuration, I understand that data consistency/availability is
on an "as things propagate" basis.
However, I did not expect to see an actual exception thrown on a normal query
using 'get_columns_since'.
I think the correct behavior when a node is unable to obtain the requested data
is to simply return less data
(in this case maybe an empty list?).
Client-side I saw:
---
...i/org/apache/cassandra/Cassandra.py in recv_get_columns_since(self)
533 x.read(self._iprot)
534 self._iprot.readMessageEnd()
--> 535 raise x
536 result = get_columns_since_result()
537 result.read(self._iprot)
TApplicationException: Internal error processing get_columns_since
---
and server-side I saw:
---
ERROR [pool-1-thread-1] 2009-05-05 18:04:21,781 Cassandra.java (line 1106)
