[jira] [Updated] (CASSANDRA-4492) Large HintsColumnFamily compactions hang

["Jason Harvey (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-4492?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jason Harvey updated CASSANDRA-4492:
------------------------------------

    Description: 
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 I can see about sending them directly.

This ring was upgraded from 1.0.7. I didn't keep any hints from the upgrade.
