---------------------------------------
Summary: Large HintsColumnFamily compactions hang
Key: CASSANDRA-4492
URL: https://issues.apache.org/jira/browse/CASSANDRA-4492
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.0.11
Reporter: Jason Harvey
Priority: Minor
Running into an issue on a 6 nodes 1.0.11 ring where whenever a somewhat large
set of hints build up (seen as low as 400MB), compaction on the hints CF hangs
indefinitely. Nothing of note in the logs. In some cases, the compaction hangs
before a tmp sstable is even created.
I've wiped out every hints sstable I have and restarted several times. The
issue always comes back rather quickly and predictably after wiping the
sstables. Compaction always seems to succeed if the hints CFs are rather small.
Hints are enabled, and my hint window is the default of 1hr. I do have some
copies of HintsColumnFamily sstables that do replicate this issue. However, the
hints may contain confidential data. If they'd be helpful in troubleshooting
this issue, let me know and see about sending them directly.
This ring was upgraded from 1.0.7. I didn't keep any hints from the upgrade.
