[jira] [Commented] (CASSANDRA-8429) Stress on trunk fails mixed
workload on missing keys
[ https://issues.apache.org/jira/browse/CASSANDRA-8429?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14236997#comment-14236997 ]
Ariel Weisberg commented on CASSANDRA-8429:
-------------------------------------------
Ok... bisecting off of trunk points to 9c316e7858f6dbf9df892aff78431044aa104ed9
I am ran the commit before e60a06cc866e5e85d3e58f25b98f8c048d07ad24 to make sure it doesn't fail. It usually fails in two tries. I have done four and it seems to work.
Two others have tried to reproduce the issue and not had any luck. I seem to be doing something different to cause it. I am using CCM to start the one node cluster with the attached cluster.conf. Server is on Ubuntu 14.04 on a dedicated quad-core desktop with SSD, client is on a quad-core laptop, network is gig-E.
