Prasad Chakka commented on HIVE-417:
------------------------------------
One thing that isn't mentioned is that in List<bucketname, List<offset>>
column, offsets are sorted.
Another thing missing is, when an index on a partition is built then a new
partition will be created for that index table (similar to that of creating a
partition for a regular table).
We can distinguish index tables and regular tables by having a table parameter.
We can skip partition specific indexes in the first phase if it reduces amount
of work and assume indexes defined on a table can be created on all partitions.
