Jing Zhao updated HDFS-5118:
----------------------------
Description: We plan to add capability to DFSClient so that the client is
able to intentionally drop responses of NameNode RPC calls according to
settings in configuration. In this way we can do better system test for
NameNode retry cache, especially when NN failover happens. (was: 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 configuration. In
this way we can do better system test for NameNode retry cache, especially when
NN failover happens.)
