Thanks, is there a way around this for now or should I fall back to 1.1.0?

Subject: Re: 2 nodes throwing exceptions trying to compact after upgrade to 1.1.2 from 1.1.0

 

See      https://issues.apache.org/jira/browse/CASSANDRA-4411

The bug is related to LCS (leveled compaction) and has been fixed.

This may not be directly related to the upgrade to 1.1.2, but I was running on 1.1.0 for a while with no issues, and I did the upgrade to 1.1.2 a few days ago.

 

2 of my nodes started throwing lots of promote exceptions, and then a lot of the beforeAppend exceptions from then on every few minutes.  This is on the high update CF that’s using leveled compaction and compression.  The other 3 nodes are not experiencing this.  I can send entire log files if desired.

These 2 nodes now have much higher load #’s then the other 3, and I’m assuming that’s because they are failing with the compaction errors?
