Subject [jira] [Commented] (HIVE-2599) Support Composit/Compound Keys with HBaseStorageHandler

------------------------------------

Hi Swarnim,

Would you mind taking a look at HBASE-8693? Specifically, HBase now provides a Struct for
defining compound keys, with support for composition using both field-width and delimiter-based
separation. It would be great to get these type encoders supported as first-class citizens
for bridging the gap between Hive and HBase.

Thanks,
Nick

> 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?
