> Scenario:
> * set dfs.namenode.delegation.token.max-lifetime=43200000 and dfs.namenode.delegation.token.renew-interval=28800000
> * Start 2 Spark long running Streaming applications (Yarn-client mode : 1470217907078_0001 , Yarn-cluster mode : 1470217907078_0002)
> * Let these application run for ~2 days
> * When application is running, we are injecting RM failover and NN failover randomly.
> * Kill the application
> * try to get application logs for above long running apps.
> Noticing below error message where it complaints that log aggregation service failed to init. Thus, app logs could not be gathered.
