Jeff Ferland commented on CASSANDRA-11172:
------------------------------------------
It's this: `INFO [CompactionExecutor:12750] 2016-02-16 17:47:48,642
LeveledManifest.java:415 - Adding high-level (L0)
SSTableReader(path='/mnt/cassandra/data/youtube/youtube_videos-2d16275b7ff93269bea0aac894e1abaa/youtube-youtube_videos-ka-104968-Data.db')
to candidates` repeating endlessly. That one's extra special this time because
of the L0. I'll look in our aggregation server and try to get value from the
time when it starts.
> Infinite loop bug adding high-level SSTableReader in compaction

> Key: CASSANDRA-11172
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11172
> Project: Cassandra
> Issue Type: Bug
> Components: Compaction
> Environment: DSE 4.x / Cassandra 2.1.11.969
> Reporter: Jeff Ferland
> Assignee: Marcus Eriksson
>
> Observed that after a large repair on LCS that sometimes the system will
> enter an infinite loop with vast amounts of logs lines recording, "Adding
> high-level (L${LEVEL}) SSTableReader(path='${TABLE}') to candidates"
> This results in an outage of the node and eventual crashing. The log spam
> quickly rotates out possibly useful earlier debugging.
