Leonid Shalupov created CASSANDRA-4687:
------------------------------------------
Summary: Exception: DecoratedKey(xxx, yyy) != DecoratedKey(zzz,
kkk)
Key: CASSANDRA-4687
URL: https://issues.apache.org/jira/browse/CASSANDRA-4687
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.1.5
Environment: CentOS 6.3 64-bit, Oracle JRE 1.6.0.33 64-bit, single
node cluster
Reporter: Leonid Shalupov
Priority: Critical
Under heavy write load sometimes cassandra fails with assertion error.
git bisect leads to commit 295aedb278e7a495213241b66bc46d763fd4ce66.
works fine if global key/row caches disabled in code.
