--------------------------------------
Summary: NullPointerException in Streaming During Repair
Key: CASSANDRA-6984
URL: https://issues.apache.org/jira/browse/CASSANDRA-6984
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Tyler Hobbs
Assignee: Yuki Morishita
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:
