Description

#create cluster
ccm create --cassandra-version git:cassandra-1.2 test
ccm populate -n 1
ccm start

#run stress
ccm node1 stress -n 10000000 -o insert
ccm node1 compact

cd ~/.ccm/test/node1/data
../bin/sstablesplit -n 100 ./Keyspace1/Standard1/Keyspace1-Standard1-ic-16-Data.db

#Expected
single large sstable should be split into multiple sstables with max size 100 MB

#Actual
ERROR 10:14:06,992 Error in ThreadPoolExecutor
java.lang.NullPointerException

Notes: It seems like the split occurs and can be recompacted.
Last known commit where split was working on 1.2 branch: 47b2cd6620894bf0c4c4584036eab49a2e14a50e
Have not bisected further.

sstablesplit is also broken on 2.0 branch; however, it fails differently. Filing separate bug on that.
