Hi all, Does YARN provide application level info ?!
For example : there is a map-reduce job persisting its outcome in a NoSql datastore by executing an INSERT command. Can YARN provide the execution time for the INSERT ? without the application itself is not logging the info anywhere. There's some argument at workplace , Dev team asking prod-support to find such info thru YARN logs. I believe "YARN's resource reporting" is similar to "unix top" command, but at cluster level . "top" give system level info , not how many INSERTs a job executed. Similarly YARN will not give application specific info like the number of INSERT op OR record count OR array size with a job , the application needs to log such info as needed. Could anyone please clarify if my understanding correct ?! Regards, Rajila
