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.
