             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.
