Naganarasimha G R updated YARN-4307:
------------------------------------
    Attachment: YARN-4307.v1.002.patch

Hi [~vvasudev],
I have uploaded a new patch with modifications for your comments
bq. Can we add the AM blacklisted nodes and the nodes blacklisted by the RM in to the app
attempt info and expose both of these via webservices? Both fields should be a part of the
rmAppAttempt.
earlier patch was also exposing these info in  app attempt info. In the latest patch have
taken case for {{RMAppAttempt}}

scheduler logs found that localhost was blacklisted but in the UI (app& apps listing page)
count was shown as zero and as well no hosts listed in the app page.
