> The test plan is to simulate 'n' number of users fire 'm' number of queries at Atlas simultaneously. This is accomplished with the help of Apache Jmeter.
> Atlas is populated with 10,000 tables. 
> • 6000 small sized tables (10 columns)
> • 3000 medium sized tables (50 columns)
> • 1000 large sized tables (100 columns)
>  The test plan consists of 30 users firing a set of 3 queries continuously for 20 times in a loop. Added -Xmx10240m -XX:MaxPermSize=512m to ATLAS_OPTS . Zookeeper throws exceptions when the test plan is run and Jmeter starts firing queries.
