Hello,

I am using Sandbox HDP 3.0, my Zeppelin UI is not running. I have included the content of the log file, have everyone see it and help me fix it. Thanks very much!

@ThanhP

The log says the opposite "Started ServerConnector@7692d9cc{HTTP/1.1,[http/1.1]}{0.0.0.0:9995}" I think you should be hitting the wrong port or IP.

How have you set up your network? Bridged/NAT, can you share the output of

$ ifconfig

If you are launching Zeppelin through Ambari Login to Ambari (operations console) as user amy_ds/amy_ds username/password combination.

http://sandbox-hdp.hortonworks.com:9995

Please share your feedback

@Shelton

I set up the network according to Bridged.
Content after executing ifconfig command:

[root@sandbox-hdp ~]# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 172.18.0.2 netmask 255.255.0.0 broadcast 172.18.255.255

TX packets 561068 bytes 229694283 (219.0 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

I checked the configuration in the zeppelin-site.xml file:

<property>
<name>zeppelin.server.addr</name>
<value>0.0.0.0</value>
</property>

<property>
<name>zeppelin.server.port</name>
<value>9995</value>
</property>

Thanks for watching and just help, thank you!

@ThanhP

As reiterated Only Adpater1 should be active with bridged Adapter and Adapter2, Adapter3, Adapter4 not activated. If so restart your sandbox and on the Splash UI [Balck window] you should see a class C IP address a 192.168.x.x use that http://192.168.x.x :9995

let me know

@Shelton

I checked the network configuration as you instructed, restarted Sandbox Hortornworks when Zeppelin UI was running

Thank you very much!
