Suresh Srinivas commented on HDFS-5118:
---------------------------------------
Comments:
- DummyRetryInvocationHandler should move from test to src as a class with
enough explanation about it is test only. Is LossyRetryInvocationHandler a
better name?
- Changes in Hdfs and DistributedFileSystem can be avoided, if this
configuration is handled in DFSClient.

> We plan to extend the current LoadGenerator so that the client is able to
> intentionally drop responses of NameNode RPC calls according to settings in
