Sergey Shelukhin updated HIVE-11689:
------------------------------------
Attachment: HIVE-11689.01.patch
Fix CS to not be global; it's not thread-safe in a sense that multiple threads
will get random futures from queue if they use it together, I didn't realize
multiple input initializers will collide 0_o
> minor flow changes to ORC split generation

> There are two changes that would help future work on split PPD into HBase
> metastore.
> 1) Move non-HDFS split strategy determination logic into main thread from
> threadpool.
> 2) Instead of iterating thru the futures and waiting, use CompletionService
> to get futures in order of completion. That might be useful by itself.
