Subject [jira] [Commented] (CASSANDRA-12512) compaction-stress: assertion error on accessing Schema.instance from client-mode tool
Date Sun, 21 Aug 2016 04:19:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12512?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15429576#comment-15429576
] 

Wei Deng commented on CASSANDRA-12512:
--------------------------------------

Yep, after applying this [patch|https://issues.apache.org/jira/secure/attachment/12824146/0001-Replaced-using-CFMetaData.compile-in-cassandra-stres.patch],
I was able to get compaction-stress to work.

To apply the patch cleanly, the additional import packages needed to be manually inserted
but it was trivial.

> Probably another code path not covered by CASSANDRA-8143? From the [comment|https://issues.apache.org/jira/browse/CASSANDRA-8143?focusedCommentId=14802787&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14802787]
it appears that this should no longer happen after the patch and I confirmed the patch is
in the code I'm using.
> To be exact for reproduce, I'm building from trunk with this commit hash (Aug 20, 2016):
