Description
Patch carried over from HBASE-9775 parent issue. Adds to the TestClientNoCluster#main a rig that allows faking many clients against a few servers and the opposite. Useful for studying client operation.
Includes a few changes to pb makings to try and save on a few creations.
Also has an edit of javadoc on how to create an HConnection and HTable trying to be more forceful about pointing you in right direction (lhofhansl – mind reviewing these javadoc changes?)
I have a +1 already on this patch up in parent issue. Will run by hadoopqa to make sure all good before commit.
