Review request for hive, Jesús Camacho Rodríguez, Zoltan Haindrich, and Vineet
Garg.
Bugs: HIVE-21948
https://issues.apache.org/jira/browse/HIVE-21948
Repository: hive-git
Description (updated)
-------
Implement parallel processing in Pre Upgrade Tool
=================================================
Process tables paralelly using a thread pool for each. Thread pools size can be
defined by command line options. If no options are given the default pool size
is the number of cpu cores.
I had to remove database parallel processing because the ForkJoinPool
implementation does not support nested parallel streams.
