[CARBONDATA-1912] Handling lock issues
Description :
Getting error trace in spark-sql console while executing compaction and
alter table rename commands.
Scenario:
execute compaction and alter table rename queries in spark - sql
Even though operation is success , getting error trace on the console
Solution: In compaction we are already handling unlock after operation , so
we can handle unlock in catch block instead of finally block.
In alter table rename operation: no need to unlock file on old location
which will result error due to table name change.

We are unlocking lock file after compaction, so added unlock operation at
required places.
