> -----------------------------------------------
>
> Key: CASSANDRA-6984
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6984
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Tyler Hobbs

> In cassandra-2.0, I can trigger a NullPointerException with a repair. These steps should reproduce the issue:
> * create a three node ccm cluster (with vnodes)
> * start a stress write (I'm using {{tools/bin/cassandra-stress --replication-factor=3 -n 10000000 -k -t 1}})
> * stop node3 while stress is running, then wait a minute
> * start node 3
> * run "ccm node3 repair"
> In the logs for node1, I see this:
> {noformat}
