Date Fri, 13 Sep 2013 17:45:53 GMT
Daniel Meyer created CASSANDRA-6026:
---------------------------------------

             Summary: NPE when running sstablesplit on valid sstable
                 Key: CASSANDRA-6026
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6026
             Project: Cassandra
          Issue Type: Bug
         Environment: Environment: java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode)

(Sun jvm on mac)
            Reporter: Daniel Meyer
             Fix For: 1.2.9


#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
        at org.apache.cassandra.io.sstable.SSTableDeletingTask.run(SSTableDeletingTask.java:70)

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.
