Andrew Chung created REEF-563:
---------------------------------

             Summary: Evaluators that are kept alive are not able to re-register with the driver
                 Key: REEF-563
                 URL: https://issues.apache.org/jira/browse/REEF-563
             Project: REEF
          Issue Type: Sub-task
            Reporter: Andrew Chung
            Assignee: Andrew Chung


This stems from 2 issues:
1. the queryUri to find the driver http endpoint is missing a '/' after application ID.
2. The driver does not recognize the evaluator trying to contact it and receives exception:
{code}
java.lang.RuntimeException: Contact from unknown Evaluator with identifier 'container_e02_1438245500443_0040_01_000004' with state 'RUNNING'
