[jira] [Created] (PIG-3742) Set MR runtime settings on tez runtime

Rohini Palaniswamy created PIG-3742:
---------------------------------------

             Summary: Set MR runtime settings on tez runtime
                 Key: PIG-3742
                 URL: https://issues.apache.org/jira/browse/PIG-3742
             Project: Pig
          Issue Type: Sub-task
            Reporter: Rohini Palaniswamy
            Assignee: Rohini Palaniswamy
             Fix For: tez-branch


Classify whether a vertex is a map or reduce and set java.opts (mapreduce.map.java.opts or mapreduce.reduce.java.opts), memory.mb (mapreduce.map.memory.mb or mapreduce.reduce.memory.mb) and env (mapreduce.map.env or mapreduce.reduce.env) accordingly on the vertex. A simple thing would be to assume all root vertexes to be map vertexes and intermediate or leaf vertexes to be reduce vertexes.
