Jing Zhao commented on HDFS-5118: --------------------------------- The patch seemed to work fine in my local test, in which I ran LoadGenerator in a 6-node HA cluster with drop-response enabled/disabled. Will see if I can add a unit test for this. > Provide testing support for DFSClient to drop RPC responses > ----------------------------------------------------------- > > 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 > Attachments: HDFS-5118.000.patch, HDFS-5118.001.patch, > HDFS-5118.002.patch, HDFS-5118.003.patch > > > 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.
