------------------------------------
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.
