Subject Re: Cannot start cassandra node anymore
Date Thu, 26 Jan 2012 15:41:05 GMT
This is on single node environment, and there is a lot of data in commit logs
needs to be flushed to sstables. So remove commit logs will cause data lost.

Fortunately, this issue happens on a new key space that have CFs that use
composite type, and we can sacrifice loosing data on this new key space.  So
we modified cassandra code so that cassandra will continue load when it
encounters this issue.  We was able to get cassandra up and running with the
modified code, and data in other key spaces remain intact. 

The schema change was that we created a new key space with composite type
CFs, but later we had to change some definition/CF names, so we dropped the
key space and recreated with new definition.
