UUID type currently not supported by parquet-mr

[asfimport]

The parquet-format project introduced a new UUID logical type in version 2.4:
https://github.com/apache/parquet-format/blob/master/CHANGES.md

This would be a useful type to have available in some circumstances, but it currently isn't supported in the parquet-mr library. Hopefully this feature can be implemented at some point.

@gszadovszky  I found it is still not present in 1.11.1 parquet-mr version. Is targeted to 1.12.0 version? If yes, could you point it is in Jira ticket please. 
When parquet-mr 1.12.0 version is planned to be released?

@vdiravka, there are some open points for 1.12.0. I think we will know more about a release date after the parquet sync next week.

It seems the storage size is reduced by ~8% for the UUID column.
