Hi Ram, The table exists and I don't get any error while running the program(i would get an error if the table did not exist). I am running a distributed cluster.
Tried following additional ways also: 1. I tried loading the AggregationImplementation coproc. 2. I also tried adding the coprocs while the table is enabled. Also had a look at the JUnit test cases and could not find any difference. I am going to try adding the coproc along with jar in Hdfs and see what happens.
