Rohith Sharma K S commented on YARN-8627:
-----------------------------------------
Thanks [~tarunparimi] for the patch. One question is how does
"/ats/done/1500089190015/0000/017/application_1500089190015_17219/application_1500089190015_17219"
created? I think we should find root cause for this. I suspect moving from
active to done directory has problem. What will happen if folder path as
appid/appid/appid?
