Description

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); }

}
}
