Hi, @Haripriya It looks like there are some problems in your master flags.

or if its some bug.
According to the screenshot you attached, the hostnames are incorrect on
your servers. Mesos WebUI depends on that to find the leading master.
A workaround is to specific the `--hostname` flag when starting your
masters. For example, launch your masters with
```
$ mesos-master --hostname=socrates-nid000xxx.us.cray.com xxx
```

passing cluster? I have a config file named cluster in /etc/mesos-master/
and when I restart the cluster it picks up the config files.
You need to ensure the flags of every master contains
`--cluster=your_cluster_name`.
Could you perform `ps aux |grep mesos-master` on every master and paste
their outputs here?
