The above relate to source level compatibility. Recompilation of a client program may be terminated
with the message "client class C is not abstract and does not override abstract method M in
TYPE". According to our compatibility guidelines we are allowed to add methods to interfaces,
so these are ALLOWED.  Please let me know if you disagree.

----

package org.apache.hadoop.hbase.ipc
class AsyncRpcClient

AsyncRpcClient has been removed. It was not Public. This change is ALLOWED.
