> LLAP: Fast llap io with slow processing pipeline can lead to OOM

> Key: HIVE-18269
> URL: https://issues.apache.org/jira/browse/HIVE-18269
> Project: Hive
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: Prasanth Jayachandran
> Assignee: Sergey Shelukhin
> Attachments: HIVE-18269.01.patch, HIVE-18269.1.patch,

>
> pendingData linked list in Llap IO elevator (LlapRecordReader.java) may grow
> indefinitely when Llap IO is faster than processing pipeline. Since we don't
> have backpressure to slow down the IO, this can lead to indefinite growth of
> pending data leading to severe GC pressure and eventually lead to OOM.
> This specific instance of LLAP was running on HDFS on top of EBS volume
> backed by SSD. The query that triggered this is issue was ANALYZE STATISTICS
> .. FOR COLUMNS which also gather bitvectors. Fast IO and Slow processing case.
