             Summary: LP Bug: 1443597 - DcsServer should generate INFO event to log when waiting on DcsMaster start
                 Key: TRAFODION-1167
                 URL: https://issues.apache.org/jira/browse/TRAFODION-1167
             Project: Apache Trafodion
          Issue Type: Bug
          Components: connectivity-dcs
            Reporter: Matt Brown
            Assignee: Matt Brown
             Fix For: 2.0-incubating


DcsMaster and DcsServers are started independently by the bin/dcs-start.sh script. DcsServers always check that DcsMaster is started in the getMaster() method shown below. A LOG.info event should be added so that user can see that DcsServers are waiting on Dcsmaster to start.

   private void getMaster() {
        boolean found = false;

        while (!found) {
            try {
                Stat stat = zkc.exists(parentZnode
                        + Constants.DEFAULT_ZOOKEEPER_ZNODE_MASTER, false);
                if (stat != null) {
                    List<String> nodes = zkc.getChildren(parentZnode
                            + Constants.DEFAULT_ZOOKEEPER_ZNODE_MASTER, null);
                    if (!nodes.isEmpty()) {
                        StringTokenizer st = new StringTokenizer(nodes.get(0),
                                ":");
                        while (st.hasMoreTokens()) {
                            masterHostName = st.nextToken();
                            port = Integer.parseInt(st.nextToken());
                            portRange = Integer.parseInt(st.nextToken());
                            masterStartTime = Long.parseLong(st.nextToken());
                        }
                        found = true;
                    }
                }

                if (!found) {
                    try {
                        Thread.sleep(5000);
                    } catch (InterruptedException e) {
                    }
                }

            } catch (Exception e) {
                e.printStackTrace();
                LOG.error(e);
            }
        }
    }
