Subject [jira] [Commented] (CASSANDRA-8879) Alter table on compact storage broken
Date Tue, 17 Nov 2015 17:11:11 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15009044#comment-15009044
] 

Aleksey Yeschenko commented on CASSANDRA-8879:
----------------------------------------------

Committed as [5414950d6a42a2f7d41dec6427cbf210dd7d99af|https://github.com/apache/cassandra/commit/5414950d6a42a2f7d41dec6427cbf210dd7d99af]
to 2.1 and merged with 2.2, 3.0, 3.1, and trunk.

Full disclosure: 2.2 dtests look good (enough), 3.0 dtests are a consistent mess of timeouts.
The ones that aren't timeout related are all non-related to this patch, and I'm sure that
none of the remaining ones are.

> In 2.0 HEAD, alter table on compact storage tables seems to be broken. With the following
table definition, altering the column breaks cqlsh and generates a stack trace in the log.
