-----------------------------------

             Summary: Clean up/fix PartitionNameWhitelistPreEventListener
                 Key: HIVE-3970
                 URL: https://issues.apache.org/jira/browse/HIVE-3970
             Project: Hive
          Issue Type: Improvement
          Components: Metastore
    Affects Versions: 0.11.0
            Reporter: Kevin Wilfong
            Assignee: Kevin Wilfong


There are a number of issues and things which can be cleaned up related to PartitionNameWhitelistPreEventListener.

* It's an event listener, but it really doesn't need to be given that the regex whitelist
is configurable, it could just be a utility method.
* It's not run when a partition is renamed, so partitions with invalid characters can be created
in this way.
* There's no easy way to check if a partition contains invalid characters before creating
it and seeing if it fails.

Most importantly, when a dynamic partition contains an invalid character, the directory for
this partition is created, and the data is moved into it, but the partition fails to be created
leaving an orphan directory.
