Review comment:
very valid question, the problem here is the partition spec string wont
match with the column name coming from the table metadata, so when we try to
get the partition value detail from TablePartitionSpec based on table metadata
column name we get empty .this is why i am trying to get the partition value
based on the column name specified in spec.
