stack updated HBASE-797:
------------------------
Attachment: 797.patch
Perverse patch that tinkers with accessibility using reflection. Though the
two classes are in same package, somehow default access is not letting me get
at default access members in super class Client. I'd guess its that they are
loaded by two different classloaders. Patch as is does not work in local mode.
It does when running MR. Digging.
