----------------------------------------------
Summary: Compaction error with Cassandra 1.1.4 and LCS
Key: CASSANDRA-4644
URL: https://issues.apache.org/jira/browse/CASSANDRA-4644
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.1.4
Environment: Cassandra 1.1.4, Ubuntu Lucid (2.6.32-346), Amazon EC2
m1.xlarge
Reporter: Rudolf VanderLeeden
In our 1.1.4 testcluster of 3 nodes with RF=3, KS=1, and CF=5, we are getting
an asserting error when running 'nodetool compact highscores leaderboard'. This
stops compactions on the 'leaderboard' CF summing up to 11835 pending
compactions. This error is seen only one one node.
The SSTables have originally been created on a 1.1.2 cluster with STCS and then
copied to the testcluster also with 1.1.2. Repair, cleanup, compact were OK
with STCS. Next, we changed to LCS and did again repair, cleanup, compact with
success.
Then we started to use this LCS-based testcluster intensively and created lots
of data and also large keys with millions of columns.
The assertion error in system.log :
