Adds support for custom partitioning patterns to MSCK repair table.
What changes were proposed in this pull request?
Adds support for custom partitioning patterns to MSCK repair table.
Why are the changes needed?
HCatStorer supports custom partitioning patterns when using dynamic partitioning, but Hive itself does not support this. This change adds support for non-pathological cases to Hive.
Does this PR introduce any user-facing change?
MSCK repair table with a configured custom partition pattern would previously ignore that pattern and error on finding nonstandard paths. With the code from this PR, it will respect the defined custom pattern when it extracts partition key values from the paths.
Is the change a dependency upgrade?
No
How was this patch tested?
A test was added to TestHiveMetastoreChecker to test the common kinds of custom patterns supported.
