[jira] [Updated] (APEXCORE-491) AppMaster memory based on the DAG

     [ https://issues.apache.org/jira/browse/APEXCORE-491?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sandesh updated APEXCORE-491:
-----------------------------
    Description: 
Memory requirement of the AppMaster various by the Application. 
Currently,  setting the AppMaster memory is done on the trial and error basis. 

Proposal is 
1st phase, atleast  document the back of the envelope method to calculate the AppMaster memory requirement.

2nd phase is to use the heuristics based on the DAG to auto calculate the app master memory requirement.

Memory requirement of the AppMaster various by the Application. 
Currently,  setting the AppMaster memory is more on the trial and error basis. 

Proposal is 
1st phase, atleast  document the back of the envelope method to calculate the AppMaster memory requirement.

2nd phase is to use the heuristics based on the DAG to auto calculate the app master memory requirement.
