Sylvain Lebresne reassigned CASSANDRA-6966: ------------------------------------------- Assignee: Sylvain Lebresne > Errors with Super Columns, mixup of 1.2 and 2.0 > ----------------------------------------------- > > Key: CASSANDRA-6966 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6966 > Project: Cassandra > Issue Type: Bug > Reporter: Nicolas Lalevée > Assignee: Sylvain Lebresne > > On our test cluster, we tried a upgrade of Cassandra from 1.2.11 to 2.0.6. > During the time we were running with 2 different versions of cassandra, there > was errors in the logs: > ERROR [WRITE-/10.10.0.41] 2014-03-19 11:23:27,523 OutboundTcpConnection.java > (line 234) error writing to /10.10.0.41 > java.lang.RuntimeException: Cannot convert filter to old super column format. > Update all nodes to Cassandra 2.0 first. > at > org.apache.cassandra.db.SuperColumns.sliceFilterToSC(SuperColumns.java:357) > at > org.apache.cassandra.db.SuperColumns.filterToSC(SuperColumns.java:258) > at > org.apache.cassandra.db.ReadCommandSerializer.serializedSize(ReadCommand.java:192) > at > org.apache.cassandra.db.ReadCommandSerializer.serializedSize(ReadCommand.java:134) > at org.apache.cassandra.net.MessageOut.serialize(MessageOut.java:116) > at > org.apache.cassandra.net.OutboundTcpConnection.writeInternal(OutboundTcpConnection.java:251) > at > org.apache.cassandra.net.OutboundTcpConnection.writeConnected(OutboundTcpConnection.java:203) > at > org.apache.cassandra.net.OutboundTcpConnection.run(OutboundTcpConnection.java:151) > I confirm we do have old style super columns which were designed when > cassandra was 1.0.x. > Since in our test cluster the replication factor is 1, I can see errors on > the client side, since 1 node among 2 was down. So I don't know for sure if > this error in cassandra affected the client, the time frame is too short to > be sure from the logs. -- This message was sent by Atlassian JIRA (v6.2#6252)
