NPE when running upgradesstables
--------------------------------
Key: CASSANDRA-3655
URL: https://issues.apache.org/jira/browse/CASSANDRA-3655
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.0.5
Environment: 1.0.5 + patch for
https://issues.apache.org/jira/browse/CASSANDRA-3618
Reporter: Tupshin Harper
Assignee: Tupshin Harper
Fix For: 1.0.7
Running a test upgrade from 0.7(version f sstables) to 1.0.
upgradesstables runs for about 40 minutes and then NPE's when trying to
retrieve a key.
No files have been succesfully upgraded. Likely related is that scrub (without
having run upgrade) consumes all RAM and OOMs.
Possible theory is that a lot of paths call IPartitioner's decorateKey, and, at
least in the randompartitioner's implementation, if any of those callers pass a
null ByteBuffer, they key will be null in the stack trace below.
