Siddharth Seth created TEZ-372:
----------------------------------
Summary: Make sure containers are not allocated to 'incorrect tasks'
Key: TEZ-372
URL: https://issues.apache.org/jira/browse/TEZ-372
Project: Apache Tez
Issue Type: Sub-task
Reporter: Siddharth Seth
Assignee: Siddharth Seth
Priority: Critical
Currently, containers are re-used at the same priority level - irrespective of JVM options,
local-resources etc - which implies different vertices with the same priority can end up re-using
containers.
If there's multiple initial map vertices - they can end up re-using containers and reading
incorrect split information.
This will be a stopgap fix - until TEZ-324 is fixed. Likely something as simple as blocking
re-use across vertices.
