---------------------------------
Summary: Parallelise mm directory cleaning process
Key: HIVE-22832
URL: https://issues.apache.org/jira/browse/HIVE-22832
Project: Hive
Issue Type: Improvement
Reporter: Marton Bod
Assignee: Marton Bod
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.
