I am new to elastic search. I have 1 crore documents in elastic search. So for better performance i thought to use es-hadoop.
I ran one simple query which return 4000 documents directly on elastic search and as well as with elastic search hadoop-spark also.
out put :-
elastic search - 2.5 seconds
es-hadoop -spark - 13 seconds
Why is this much difference is there any way to tune.
