restarting node crashes with NPE when, while replaying the commitlog, the 
cfMetaData is requested
-------------------------------------------------------------------------------------------------

                 Key: CASSANDRA-995
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-995
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 0.7
         Environment: SVN rev 935070
            Reporter: Ted Zlatanov


Removing the commitlog directory completely fixes this.   I can reliably 
reproduce it by 1) starting and configuring a schema with one keyspace, one 
super CF with LongType supercolumns; 2) inserting data; 3) shutting down and 
restarting the node.

Here's my schema expressed in cassidy.pl, should be obvious what the parameters 
are:
./cassidy.pl -server X -port Y -keyspace system 'kdefine test 
org.apache.cassandra.locator.RackUnawareStrategy 2 
org.apache.cassandra.locator.EndPointSnitch'
./cassidy.pl -server X -port Y -keyspace test 'fdefine Status Super LongType 
BytesType comment=statuschanges,row_cache_size=0,key_cache_size=20000'

The problem seems to be related to CASSANDRA-44 as it happens when the CF 
metadata is requested but I don't know what's causing it.
