[jira] [Created] (HDFS-5118) Extend LoadGenerator for testing NameNode retry cache

Jing Zhao created HDFS-5118:
-------------------------------

             Summary: Extend LoadGenerator for testing NameNode retry cache
                 Key: HDFS-5118
                 URL: https://issues.apache.org/jira/browse/HDFS-5118
             Project: Hadoop HDFS
          Issue Type: New Feature
    Affects Versions: 3.0.0
            Reporter: Jing Zhao
            Assignee: Jing Zhao


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.
