stack updated HBASE-1935:
-------------------------
Attachment: pscanner.patch
Here is a first attempt. Maybe someone would like to take it on? It runs
scanners against multiple regions concurrently and then aggregates the results.
Includes a unit test but needs convertion to new style client-side test (Only
two of the tests in the unit test are for parallel scanning).
