Hi all,
I was wondering if anybody had seen the following behaviour before and how we might detect it and keep the application running.

We have a 6 node cluster. It seems that one of these nodes forgot about all but one of the application column families - possibly after a restart. Then, when our application connects using Hector, it can't find any data so gives back an exception.

I'm currently running nodetool repair on one of the *other* nodes which is taking a very long time to complete. (35mins and counting a load of <9MB)

The  logs from the failing node say:
INFO [MemoryMeter:1] 2012-08-23 14:59:14,807 Memtable.java (line 213) CFS(Keyspace='system', ColumnFamily='HintsColumnFamily') liveRatio is 1.1219167666485013 (just-counted was 1.0). calculation took 28ms for 1252 columns INFO [main] 2012-08-23 14:59:14,949 CommitLogReplayer.java (line 272) Finished reading /var/lib/cassandra/commitlog/CommitLog-22654969122258

... and so on.

Hector is saying:
InvalidRequestException(why:unconfigured columnfamily user_conversations)


Thanks for any comments or advice,
Edward
