Till Rohrmann created FLINK-10415:
-------------------------------------

             Summary: RestClient does not react to lost connection
                 Key: FLINK-10415
                 URL: https://issues.apache.org/jira/browse/FLINK-10415
             Project: Flink
          Issue Type: Bug
          Components: REST
    Affects Versions: 1.5.4, 1.6.1, 1.7.0
            Reporter: Till Rohrmann
             Fix For: 1.7.0, 1.6.2, 1.5.5


While working on FLINK-10403, I noticed that Flink's {{RestClient}} does not seem to react to a lost connections in time. When sending a request to the current leader it happened that the leader was killed just after establishing the connection. Then the {{RestClient}} did not fail the connection and was stuck in writing a request or retrieving a response from the lost leader. I'm wondering whether we should introduce a {{ReadTimeoutHandler}} and {{WriteTimeoutHandler}} to handle these problems.
