Pavel Trukhanov resolved CASSANDRA-12614.
-----------------------------------------
Resolution: Invalid
It was due to somehow corrupted .data file
As we found out that Maxtimestamp in that sstable was like year 14800+ or
something.
So we fixed that timestamp (by simply overwriting data — thanks to
sstable2json) and it fixed everything
> Cassandra stops compacting
> --------------------------

> Key: CASSANDRA-12614
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12614
> Project: Cassandra
> Issue Type: Bug
> Components: Compaction
> Environment: linux cas-2.1.15
> Reporter: Pavel Trukhanov
>
> After some issues 3 out of 9 our cassandra nodes stopped to compact one
> particular cf. So we see constantly increasing number of sstables for that cf.
> While other cfs on these nodes and other nodes keep compacting.
> This cf has DTCS.
> Here's desc:
> {quote}
> CREATE TABLE okmeter.bunches (
> bunch_key text,
> bunch_ts bigint,
> version uuid,
> value blob,
> PRIMARY KEY (bunch_key, bunch_ts, version)
> ) WITH COMPACT STORAGE
> AND CLUSTERING ORDER BY (bunch_ts DESC, version ASC)
> AND bloom_filter_fp_chance = 0.01
> AND caching = '\{"keys":"ALL", "rows_per_partition":"NONE"\}'
> AND comment = ''
> AND compaction = \{'class':
> 'org.apache.cassandra.db.compaction.DateTieredCompactionStrategy',
> 'max_window_size_seconds': '3686400', 'base_time_seconds': '14400',
> 'max_sstable_age_days': '90'\}
> AND compression = {}
> AND dclocal_read_repair_chance = 0.1
> AND default_time_to_live = 0
> AND gc_grace_seconds = 864000
> AND max_index_interval = 2048
> AND memtable_flush_period_in_ms = 0
> AND min_index_interval = 128
> AND read_repair_chance = 0.0
> AND speculative_retry = '99.0PERCENTILE';
> {quote}
> I couldn't find anything interesting in logs.
> I've tried drain & restart - no luck.
> I've tried to disable/enable autocompation - nothing's changed.
> I've tried force major - it works but sstable count starts increasing after
> major is done.

> It seems that it just completely ignores autocompaction enabled.
