Marton Bod updated HIVE-22832:
------------------------------
Description: Inside Utilities::handleDirectInsertTableFinalPath, the
cleanDirectInsertDirectories method is called sequentially for each element of
the directInsertDirectories list, which might have a large number of elements
depending on how many partitions were written. This current sequential
execution could be improved by parallelising the clean up process. (was:
Inside Utilities::handleMmTableFinalPath, the cleanMmDirectories method is
called sequentially for each element of the mmDirectory list, which might have
a large number of elements depending on how many partitions were written. This
current sequential execution could be improved by parallelising the clean up
process. )
