It'll be hard to reuse this script + txt files from non-HDP stacks. Should the files be moved to common-services folder ?

> - In light of AMBARI-12983, performance would be seen if the precision table can fully utilize the allocated memstore heap.
> - With the single table getting most of the high volume reads and all of the high volume writes it is important to define a policy for splitting the Region in order to optimize performance of the scans.
