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.
