Subject [jira] [Created] (CASSANDRA-6845) Cleanup fails with IndexOutOfBoundsException exception
Date Wed, 12 Mar 2014 16:05:44 GMT
Dmitrij Koniajev created CASSANDRA-6845:
-------------------------------------------

             Summary: Cleanup fails with IndexOutOfBoundsException exception
                 Key: CASSANDRA-6845
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6845
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: CentOS Linux 2.6.32-431.el6.x86_64
Datastax Cassandra 2.0.5-1
            Reporter: Dmitrij Koniajev
         Attachments: 0001-fixed-bug-in-CompactionManager.needsCleanup.patch

Originally we had Cassandra cluster with the following configuration:
{quote}
Initial tokens:
10.1.11.51: -9223372036854775808
10.1.11.52: 0
10.2.11.51: -9223372036854775807
10.2.11.52: 1

Endpoint snitch: PropertyFileSnitch
10.1.11.51=DC1:RAC1
10.1.11.52=DC1:RAC1 
10.2.11.51=DC2:RAC1
10.2.11.52=DC2:RAC1
{quote}
We have created keyspace with network topology strategy and replication factor 2:
{quote}
CREATE KEYSPACE our_keyspace WITH replication = {
  'class': 'NetworkTopologyStrategy',
  'DC2': '2',
  'DC1': '2'
};
{quote}
All column families have been created with SizeTiered compaction strategy. Аfter a while
column families have been migrated to LeveledCompactionStrategy and then replication factor
was decreased to 1.

We started cleanup, but on non-seed nodes (10.1.11.52,10.2.11.52) it failed with assertion
error. Assertion stacktrace was the same as described in [CASSANDRA-6774|https://issues.apache.org/jira/browse/CASSANDRA-6774]
issue.
Then we've stopped all compactions, started cleanup again and got another exception:

It seems there is typo in *needsCleanup* method of *CompactionManager* class and the supplied
patch should fix the issue.
Get method on the line *502* (*CompactionManager.java*) throws exception, because of the wrong
comparison on the line *496*: there should be *sortedRanges* size check, not *ownedRanges*.
