-------------------------------------------
Hi [~apurtell] ,
We need TableMapReduceUtil.addTableCoprocessorJarsToClasspath() in
createSubmittabelJob() method, otherwise we are getting Phoenix coprocessor
classed not found error(I tried with Phoenix table).
oh my bad. I fixed 99% of nit issues in v2 patch along with removing unwanted
deletedDir() in createSubmittableJob() method. But when I generated v3 patch I
missed it.
Attaching v4 patch with all nit issues, unwanted code addressed.

> As of now VerifyReplicatin tool is running using normal HBase scanners. If
> you want to run VerifyReplication multiple times on a production live
> cluster with large tables then it creates extra load on HBase layer. So if we
> implement snapshot based support then both in source and target we can read
> data from snapshots which reduces load on HBase
