Summary: consider optimizing Utilities::handleMmTableFinalPath
Key: HIVE-15368
URL: https://issues.apache.org/jira/browse/HIVE-15368
Project: Hive
Issue Type: Sub-task
Reporter: Rajesh Balamohan
Priority: Minor
Branch: hive-14535
https://github.com/apache/hive/blob/hive-14535/ql/src/java/org/apache/hadoop/hive/ql/exec/Utilities.java#L4049
When running "insert overwrite...on partitioned table" with 2000+ partitions,
good amount of time (~245 seconds) was spent in iterating every mmDirectory
entry and checking its file listings in S3. Creating this jira to consider
optimizing this codepath, as information from {{getMmDirectoryCandidates}}
could be used in terms of reducing the number of times S3 needs to be contacted.
