----------------------------------
Summary: Too many delta files during Compaction (was: HDP 2.3 and Flume
1.6: Hive Streaming – Too many delta files during Compaction)

> Hello,
> I am streaming weblogs to Kafka and then to Flume 1.6 using a Hive sink, with
> an average of 20 million records a day. I have 5 compactors running at
> various times (30m/5m/5s), no matter what time I give, the compactors seem to
> run out of memory cleaning up a couple thousand delta files and ultimately
> falls behind compacting/cleaning delta files. Any suggestions on what I can
> do to improve performance? Or can Hive streaming not handle this kind of load?
> I used this post as reference:
