-------------------------------------

             Summary: Increase akka.ask.timeout for tests using the MiniCluster
                 Key: FLINK-23906
                 URL: https://issues.apache.org/jira/browse/FLINK-23906
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination, Tests
    Affects Versions: 1.13.2, 1.12.5, 1.14.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.14.0, 1.12.6, 1.13.3


We have seen over the last couple of weeks/months an increased number of test failures because of {{TimeoutException}} that were triggered because the {{akka.ask.timeout}} was exceeded. The reason for this was that on our CI infrastructure it can happen that there are pauses of more than 10s (not sure about the exact reason). 

In order to harden all tests relying on the {{MiniCluster}} I propose to increase the {{akka.ask.timeout}} to a minute if nothing else has been configured.
