Aleksey Yeschenko commented on CASSANDRA-12212: ----------------------------------------------- Mostly correct. "only for a very short period of time" is not true. Pre-2.1 counter cells can remain in the system potentially forever, as there is no guarantee old counter values would ever be overridden. > system.compactions_in_progress needs to be used on first upgrade to 3.0 > ----------------------------------------------------------------------- > > Key: CASSANDRA-12212 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12212 > Project: Cassandra > Issue Type: Bug > Components: Compaction > Reporter: Jeremiah Jordan > Assignee: Stefania > Fix For: 3.0.x, 3.x > > > CASSANDRA-7066 removed the system.compactions_in_progress table and replaced > it with the new transaction system. But system.compactions_in_progress needs > to be consulted for the first startup after upgrading from 2.1 to 3.0. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
