Blank home page and disconnected
Hello Experts,
I am beginning to explore Apache Zeppelin and have set it up on one of our
development cluster nodes. The hadoop version is Hadoop 2.6.0-cdh5.7.0,
Spark - 1.6, maven 3.3.9 (Had an error while building one of the
dependencies and it mentioned the version should be atleast 3.1.0)
I have set the below properties in zeppelin-env.sh
*export JAVA_HOME=/home/zeppelin/prerequisites/jdk1.7.0_79*
*export MASTER=yarn-client # Spark master
url. eg. spark://master_addr:7077. Leave empty if you want to use local
mode.*
*export
HADOOP_CONF_DIR=/etc/hadoop/conf.cloudera.yarn:/etc/hive/conf.cloudera.hive*
*export
HADOOP_HOME=/opt/cloudera/parcels/CDH-5.7.0-1.cdh5.7.0.p0.45/lib/hadoop*
*export
SPARK_HOME=/opt/cloudera/parcels/CDH-5.7.0-1.cdh5.7.0.p0.45/lib/spark*
and built as root with below command:
*mvn clean package -Pspark-1.6 -Dhadoop.version=2.6.0-cdh5.7.0 -Phadoop-2.6
-Pyarn -DskipTests*
Since default port 8080 threw address in use exception (some cloudera
services use it I guess), I changed this to 8091.
./bin/zeppelin-daemon.sh start -> works and the server is started, however,
there is nothing displayed on the home screen and the status shows
disconnected.
There are no errors in the zeppelin-root-xxx.log. Only relevant entry could
be (which I am not sure is an issue)
*INFO [2016-05-11 18:53:05,910] ({main}
StandardDescriptorProcessor.java[visitServlet]:297) - NO JSP Support for /,
did not find org.eclipse.jetty.jsp.JettyJspServlet*
The zeppelin-root-xxx.out file shows has the below entry as the latest:
*May 11, 2016 6:53:08 PM
com.sun.jersey.server.impl.application.WebApplicationImpl _initiate*
*INFO: Initiating Jersey application, version 'Jersey: 1.13 06/29/2012

Appreciate any help in this regard

Re: Blank home page and disconnected
Posted by Sunita Koppar <su...@verizondigitalmedia.com>.
Thank you for you help in resolving this Hyung. You are right, it was
related to firewall. For benefit of others in corporate world facing the
same issue, here are the details.
The initial firewall request opened http, https and web browsing only. The
firewall sees web socket as a different connection type compared to these
and blocks it. After the network engineer changed the connection type to
"websocket" based on Hyung's analysis, Zeppelin was able to connect.

Re: Blank home page and disconnected

I don't think pr868 is the reason. It seems your problem is the network
issue.
Can you do the websocket connection test on
http://www.websocket.org/echo.html and share your result?

Re: Blank home page and disconnected
Posted by Sunita Koppar <su...@verizondigitalmedia.com>.
Appreciate your quick responses. Thanks a lot.
I am trying with this exact combination. Its a CDH 5.7 cluster with Spark
1.6
https://github.com/apache/incubator-zeppelin/pull/868 could this be the
reason?
Any suggestions on how to debug the issue. I dont see any errors anywhere.
regards

Re: Blank home page and disconnected

Since 0.5.5 version, Zeppelin uses single port for REST and websocket so
you don't need to care about 8092 port in your case.

Thanks for the response.
Yes there is a firewall but that has been opened for access. The zeppelin
server runs on 8091 and that is open. From the comments, it seems 8092
needs to be open as well. From firewall perspective 8092 is open as well
(we have requested for a bracket of sockets to be opened which includes
8092), but I am not sure if zeppelin client opens the websocket over
existing connection or as an independent socket connection from browser
back to server. Pardon my ignorance on the subject.
Here is the netstat output of the node running the server:

Re: Blank home page and disconnected

Hello.
Zeppelin uses websocket connection. Do you have some firewall/proxy between
your browser and zeppelin server daemon? If that does not pass websocket
connection, start page may show 'Disconnected'.
