When Hmaster crashed  and restart , The Hmaster is hung up.

    // start up all service threads.
    startServiceThreads();                                  ----this open port failed!

    // Wait for region servers to report in.  Returns count of regions.
    int regionCount = this.serverManager.waitForRegionServers();

    // TODO: Should do this in background rather than block master startup

    // Make sure root and meta assigned before proceeding.
assignRootAndMeta();                                       --- hung up this function, because
of root can't be assigned.

  if (!catalogTracker.verifyRootRegionLocation(timeout)) {
      this.catalogTracker.waitForRoot();                   --- This statement code is hung
