[jira] [Created] (HIVE-20025) Clean-up of event files created by HiveProtoLoggingHook.

Sankar Hariappan created HIVE-20025:
---------------------------------------

             Summary: Clean-up of event files created by HiveProtoLoggingHook.
                 Key: HIVE-20025
                 URL: https://issues.apache.org/jira/browse/HIVE-20025
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2
    Affects Versions: 3.0.0
            Reporter: Sankar Hariappan
            Assignee: Sankar Hariappan
             Fix For: 4.0.0


Currently, HiveProtoLoggingHook write event data to hdfs. The number of files can grow to very large numbers.

Since the files are created under a folder with Date being a part of the path, hive should have a way to clean up data older than a certain configured time / date. This can be a job that can run with as little frequency as just once a day.

This time should be set to 1 week default. There should also be a sane upper bound of # of files so that when a large cluster generates a lot of files during a spike, we don't force the cluster fall over.
