Subject [jira] [Commented] (CASSANDRA-8696) nodetool repair on cassandra 2.1.2 keyspaces return java.lang.RuntimeException: Could not create snapshot
Date Wed, 22 Apr 2015 21:56:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8696?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14507997#comment-14507997
] 

Russ Hatch commented on CASSANDRA-8696:
---------------------------------------

I have seen this issue occur with regularity when repairs are initiated by opscenter's repair
service. First time it occured I had indeed altered the RF in the course of testing.

Second time I used an RF of 3 from the beginning and didn't alter it.

While opscenter is running repairs I'm writing data using cassandra-stress, writes with CL.ONE.

Interestingly it seems to occur much more often when stress is running and adding load to
the cluster with a pure write workload. When I stop stress the opscenter initiated repairs
seem to succeed from that point forward. If I start stress writes again, the same snapshot
exception starts cropping up again.
