Subject Re: endpoint coprocessor
Date Thu, 10 Apr 2014 12:06:27 GMT
Here is a reference implementation for aggregation :
http://search-hadoop.com/c/HBase:hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/AggregateImplementation.java||Hbase+aggregation+endpoint

You can find it in hbase source code. 
Cheers
