Subject [jira] [Commented] (YARN-422) Add AM-NM client library
Date Wed, 24 Apr 2013 17:11:17 GMT

    [ https://issues.apache.org/jira/browse/YARN-422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13640660#comment-13640660

Zhijie Shen commented on YARN-422:
----------------------------------

Yes, non-blocking API is a must, but shall we define AMNMClientImpl the simple wrapper around
the RPC (but to all NMs), such that it contain blocking APIs? After that, we define another
class, called AMNMClientAsync, to further wrap AMNMClientImpl and provide non-blocking APIs.
Similar to what we did in AMRMClientImpl and AMRMClientAsync. How do you think?
