Subject Re: parallel processing of regions in coprocessor
Date Wed, 01 Mar 2017 22:55:46 GMT
It is something like map reduce processing.
I want to run map and combine phase inside in a coprocessor for every
region separately, return partial results to the client. On the client
invoke reduce phase and store result in another hbase table.
