[jira] [Created] (TEZ-993) Remove application logic from RecoveryService

Bikas Saha created TEZ-993:
------------------------------

             Summary: Remove application logic from RecoveryService
                 Key: TEZ-993
                 URL: https://issues.apache.org/jira/browse/TEZ-993
             Project: Apache Tez
          Issue Type: Sub-task
            Reporter: Bikas Saha


Currently RecoveryService storage logic knows a lot about the DAG like which dag is pre-warm and does not need to be stored, which events needs special treatment etc. This kind of logic couples the DAG and the storage more than is probably necessary and can be a source of complications down the road. The storage should ideally be simply storing a sequence of arbitrary records delimited by a marker.
