    • Type: Bug

    • Priority: Major
    • Resolution: Not A Problem
    • Affects Version/s: 2.1.0
    • Fix Version/s: None
    • Component/s: Web UI

    • Environment:

      ppc64le GNU/Linux, POWER8, only master node is reachable externally other nodes are in an internal network

      Description

      When reverse proxy is enabled

      spark.ui.reverseProxy=true
      spark.ui.reverseProxyUrl=/

      first of all any invocation of the spark master Web UI hangs forever locally (e.g. http://192.168.10.16:25001) and via external URL without any data received.
      One, sometimes two spark applications succeed without error and than workers start throwing exceptions:

      Caused by: java.io.IOException: Failed to connect to /192.168.10.16:25050

      The application dies during creation of SparkContext:

      2017-05-22 16:11:23 INFO StandaloneAppClient$ClientEndpoint:54 - Connecting to master spark://node0101:25000...

      .....
      Caused by: java.lang.IllegalArgumentException: requirement failed: Can only call getServletHandlers on a running MetricsSystem

      This definitively does not happen without reverse proxy enabled!
