[jira] [Created] (FLINK-1581) Configure DeathWatch parameters properly

Till Rohrmann created FLINK-1581:
------------------------------------

             Summary: Configure DeathWatch parameters properly
                 Key: FLINK-1581
                 URL: https://issues.apache.org/jira/browse/FLINK-1581
             Project: Flink
          Issue Type: Bug
            Reporter: Till Rohrmann


We are using Akka's DeathWath mechanism to detect failed components. However, the interval until an {{Instance}} is marked dead is currently very long. Especially, in conjunction with the job restarting mechanism we should devise a mechanism which either quickly detects dead {{Instance}}s or  set the interval, pause and threshold values such that the detection does not take longer than the Akka ask timeout value. Otherwise, all retries might be consumed before an {{Instance}} is recognized being dead.

Further investigation of the correct failure behavior is necessary.
