Review comment:
Do we need the alterPartitionNoTxn with the following signature anymore
private Partition alterPartitionNoTxn(String catName, String dbname, String
name,
List<String> part_vals, Partition newPart, String validWriteIds,
Ref<MColumnDescriptor> oldCd)
Even single alter partition can use the same call with the table already
passed. Will not result to any improvement but just a clean up of the code.
