Description
This looks like a regression where org.apache.hadoop.hbase.client.ConnectionFactory#createConnection(org.apache.hadoop.conf.Configuration, java.util.concurrent.ExecutorService) even though supports ExecutorService but has stopped working for ForkJoinPool and throws java.lang.ClassCastException: java.util.concurrent.ForkJoinPool cannot be cast to java.util.concurrent.ThreadPoolExecutor, possibly due to HBASE-22244
I have been able to write a UT to verify the same and ran it on a branch not having above-mentioned change (HBASE-22244) i.e. branch-2.1 where the test passes while for branch-2, having this change, the test fails with following:

Also it worth noting that the issue does not exist in master, i think its because of HBASE-21723 which removes `ConnectionImplementation` from master.
