Subject [jira] [Commented] (HADOOP-14957) ReconfigurationTaskStatus is exposing guava Optional in its public api
Date Fri, 20 Oct 2017 21:19:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14957?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16213259#comment-16213259
] 

Haibo Chen commented on HADOOP-14957:
-------------------------------------

Any client that's not directly calling the ClientDatanodeProtocol method in question should
be fine given the .proto data is unchanged as you point out. 
Looks like it is just used in DFS Admin protocol, not sure how pervasive it is used. [~xiaochen]
[~andrew.wang].

I have attached a patch that I have tested internally to make sure it does not cause build
failures for downstream projects, in case we decide to change it.
