Always ensure enough space for Compaction
-----------------------------------------
Key: CASSANDRA-3985
URL: https://issues.apache.org/jira/browse/CASSANDRA-3985
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.0.7
Reporter: Aaron Morton
Assignee: Aaron Morton
Priority: Minor
>From http://www.mail-archive.com/user@cassandra.apache.org/msg20757.html
CompactionTask.execute() checks if there is a valid compactionFileLocation only
if partialCompactionsAcceptable() . upgradesstables results in a CompactionTask
with userdefined set, so the valid location check is not performed.
The result is a NPE, partial stack
{code:java}
$ nodetool -h localhost upgradesstables
Error occured while upgrading the sstables for keyspace MyKeySpace
