Marcus Eriksson commented on CASSANDRA-10270:
---------------------------------------------
In 2.2 nodetool compact is actually going to do a major compaction on LCS as
well: https://github.com/apache/cassandra/blob/cassandra-2.2/NEWS.txt#L64
The warnings are expected as well, we drop ancestor information when there are
many sstables involved in the compactin since every new sstable would have all
old sstables as ancestors
> Cassandra stops compacting

> Key: CASSANDRA-10270
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10270
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: linux (google cloud click-to-deploy, default settings, 3
> nodes)
> Reporter: Adam Bliss
> Assignee: Marcus Eriksson
> Priority: Critical
> Fix For: 3.0.0 rc1, 2.2.2

> My cassandra cluster won't keep compacting. I notice that if I restart, it
> does compact for a while, but after a time it stops. As a result, after
> adding a bunch of rows, I ended up with about 1000 sstables per node.
> I'll attach more logs in a minute, but it seems like this might be the most
> relevant part:
