Subject [jira] [Commented] (YARN-5955) Use threadpool or multiple thread to recover app
Date Sun, 04 Dec 2016 01:09:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5955?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15719048#comment-15719048

Naganarasimha G R commented on YARN-5955:

Yes [~templedf], we started of with YARN-4494 as the base idea, with focus of "fast recovery
using async calls and multiple threads". We have come up less modifications on the zoo keeper
structure too. We have incorporated "async calls and multiple threads" and tested extensively
in our test clusters and results seem to be promising and as [~varun_saxena] mentioned, we
will come up design doc and initial patch.
We also wanted to incorporate YARN-2962 to have it under one umbrella, as its important for
large clusters.
