Andrew Purtell commented on HBASE-11936:
----------------------------------------
Sorry.
This says moving a method upward in the class hierarchy is fine:
http://docs.oracle.com/javase/specs/jls/se7/html/jls-13.html
This much older one - http://www.cs.cornell.edu/andru/javaspec/13.doc.html -
says the same but additionally "provided a forwarding method is left in its
place".
I'm not an expert on Java binary compatibility.

> The Get operation is implemented in HBase as a Scan. The default isolation
> level for Scan is READ_COMMITTED. The API to change the isolation level is
> part of Scan class and there is no way for Get operation to change this from
> default. We should move this API up to Query (which is a parent of both: Scan
> and Get).
