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.
