TEZ-4349 DAGClient gets stuck with invalid cached DAGStatu The `cachedDagStatus` should be valid for a certain amount of time, or certain number of retires. When the `cachedDAGStatus` expires, the DAGClient tries to pull from AM or the RM. An error in fetching the status from both AM and RM, would return null to the caller. - The expiration time can be configured using `TezConfiguration.TEZ_CLIENT_DAG_STATUS_CACHE_TIMEOUT_MINUTES` `tez.client.dag.status.cache.timeout-minutes`, and the default is 5. The `timeUnit` of the expiration is minutes. - Added a new UT `TestDAGClient.testGetDagStatusWithCachedStatusExpiration` - ran the following unit tests: `mvn test -Dtest=TestDAGClient,TestTezClient,TestMockDAGAppMaster` -- This is an automated message from the Apache Git Service.
