[jira] [Created] (SPARK-10612) Add prepare to LocalNode

Reynold Xin created SPARK-10612:
-----------------------------------

             Summary: Add prepare to LocalNode
                 Key: SPARK-10612
                 URL: https://issues.apache.org/jira/browse/SPARK-10612
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
            Reporter: Reynold Xin
            Assignee: Reynold Xin


The idea is that we should separate the function call that does memory reservation (i.e. prepare) from the function call that consumes the input (e.g. open()), so all operators can be a chance to reserve memory before they are all consumed.
