Anton Winter created CASSANDRA-4411:
---------------------------------------
Summary: Assertion with LCS compaction
Key: CASSANDRA-4411
URL: https://issues.apache.org/jira/browse/CASSANDRA-4411
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.1.2
Reporter: Anton Winter
As instructed in CASSANDRA-4321 I have raised this issue as a continuation of
that issue as it appears the problem still exists.
I have repeatedly run sstablescrub across all my nodes after the 1.1.2 upgrade
until sstablescrub shows no errors. The exceptions described in CASSANDRA-4321
do not occur as frequently now but the integrity check still throws exceptions
on a number of nodes. Once those exceptions occur compactionstats shows a
large number of pending tasks with no progression afterwards.
