Brock Noland commented on HIVE-2599:
------------------------------------
bq. But there are increasing number of cases where custom and more complicated
serializers are written to serialize the keys in a more efficient way (salting
is such an example)
I've seen this as well. That is where a simple struct cannot deserialize a key.

> It would be really nice for hive to be able to understand composite keys from
> an underlying HBase schema. Currently we have to store key fields twice to be
> able to both key and make data available. I noticed John Sichi mentioned in
> HIVE-1228 that this would be a separate issue but I cant find any follow up.
> How feasible is this in the HBaseStorageHandler?
