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

             Summary: Remove unnecessary thread blocking in RestClient#submitRequest
                 Key: FLINK-8463
                 URL: https://issues.apache.org/jira/browse/FLINK-8463
             Project: Flink
          Issue Type: Bug
          Components: REST
    Affects Versions: 1.5.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.5.0


The {{RestClient}} unnecessarily blocks an IO executor thread when trying to open a connection to a remote destination. This can be improved by registering a {{ChannelFuture}} listener which continues the execution once the connection has been established.
