             Summary: Add high availability support for Yarn
                 Key: FLINK-2790
                 URL: https://issues.apache.org/jira/browse/FLINK-2790
             Project: Flink
          Issue Type: Sub-task
            Reporter: Till Rohrmann


Add master high availability support for Yarn. The idea is to let Yarn restart a failed application
master in a new container. For that, we set the number of application retries to something
greater than 1. 

>From version 2.4.0 onwards, it is possible to reuse already started containers for the
TaskManagers, thus, avoiding unnecessary restart delays.

>From version 2.6.0 onwards, it is possible to specify an interval in which the number
of application attempts have to be exceeded in order to fail the job. This will prevent long
running jobs from eventually depleting all available application attempts.
