@ssathish Thank you!
I'm having few more doubts, 1. As mentioned in this link https://hortonworks.com/blog/apache-hadoop-yarn-concepts-and-applications/ it says "The application code executing within the container then provides necessary information (progress, status etc.) to its ApplicationMaster via an application-specific protocol.", so how the application master monitor the status of containers which are running on different node than applicatioMaster. 2. Also as you mentioned its nodemanager which will communicate with container, so can nodemanager directly communicate with containers which are running on different nodes or it will go through RM to get container information.
Thank you.

If I'm having a column with BIGINT as datatype and it's having a value in INT's range, then will it take all the 8bytes or just 4bytes for storing? ,
what about BIGINT and INT? for example if I'm having a column with BIGINT as datatype and I'm inserting value in INT's range, will it take 8byte(as for BIGINT) or just 4bytes considering it is in INT range?
