Subject [jira] [Commented] (HDFS-10207) Support enable Hadoop IPC backoff without namenode restart
Date Thu, 14 Apr 2016 23:01:25 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10207?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15242094#comment-15242094
] 

Xiaoyu Yao commented on HDFS-10207:
-----------------------------------

One additional comments on the patch: backoff reconfigure is added for both client/service/lifeline
ports. This is not necessary as we never want to backoff rpc requests on service and lifeline
port. We only need to support reconfigure backoff for client rpc port.

> It will be useful to allow changing {{ipc.#port#.backoff.enable}} without a namenode
restart to protect namenode from being overloaded.
