Subject [jira] [Commented] (HDFS-12329) Ozone: Ratis: Readonly calls in XceiverClientRatis should use sendReadOnly
Date Wed, 20 Sep 2017 02:00:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12329?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16172612#comment-16172612

Weiwei Yang commented on HDFS-12329:

+1 to the v4 patch, the findbugs and javadoc warnings are not caused by this patch, I am not
sure why they are showing up here. Also the test failure seems not related too. The jenkins
job result is a bit messed up right now.

> Currently both write and readonly calls in Ratis use RaftClient.send which enqueues the
the request to the raft log and is processed later when the log entry is consumed.
> Readonly call can be optimized by using RaftClient.sendReadOnly which will directly query
the RaftServer for a particular request.
> This jira will be used to discuss this issue.
