Samarth Jain commented on PHOENIX-3346:
---------------------------------------

Thank you, [~sergey.soldatov]. Sorry for being on your case. Just trying to get builds stabilized
for our 4.10 release. It looks like the newly added hive tests are not completing. See this
crawler report  - https://builds.apache.org/job/PhoenixFindTestTimeout/538/console

> If column mapping is used during table creation, the hive table becomes  unusable and
throws UnknownColumn exception.
> There are several issues in the current implementation:
> 1. During table creation mapping doesn't applies to primary keys
> 2. During select query building no mapping happen
> 3. PhoenixRow should have backward mapping from phoenix column names to hive names.
