Problem Zeppelin install HDP 2.4

rjknulst1 — Wed, 11 May 2016 02:45:54 GMT

Hi, I have followed the steps here:

http://hortonworks.com/hadoop-tutorial/apache-zeppelin-hdp-2-4/ #Installing Zeppelin on an Ambari-Managed Cluster

but the Ambari managed install fails at this script step:

2016-05-10 19:40:39,645 - Execute['/var/lib/ambari-agent/cache/stacks/HDP/2.4/services/ZEPPELIN/package/scripts/setup_snapshot.sh /usr/hdp/current/zeppelin-server/lib master2.r4p2hzj2llcexob4fgsutkohlh.ax.internal.cloudapp.net 9083 10001 master1.r4p2hzj2llcexob4fgsutkohlh.ax.internal.cloudapp.net 9995 True /var/lib/ambari-agent/cache/stacks/HDP/2.4/services/ZEPPELIN/package /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.71-2.b15.el7_2.x86_64 >> /var/log/zeppelin/zeppelin-setup.log'] {'user': 'zeppelin'}

The error is 'right' because the target dir is non-existant: there is only conf/ and notebook/

Anyone a suggestion as to how to fix this?

Hello Jasper:

It looks like Zeppelin lib directory is missing lots of things. For instance here is mine under HDP 2.4 Sandbox:

[root@sandbox lib]# cd /usr/hdp/current/zeppelin-server/lib
[root@sandbox lib]# ls -l

Did you already perform the Add Service step:

After Ambari restarts and service indicators turn green, add the Zeppelin Service: At the bottom left of the Ambari dashboard, choose Actions -> Add Service:

On the Add Service screen, select the Zeppelin service. Step through the rest of the installation process, accepting all default values. On the Review screen, make a note of the node selected to run Zeppelin service; call this ZEPPELIN_HOST.

Click Deploy to complete the installation process.

You are right Paul, it is missing a lot.

Found the problem in the meantime. On a fresh HDP 2.4 Zeppelin is not installed but there are some things prepared already like a symlink in /usr/hdp/current/zeppelin-server -> /usr/hdp/2.4.0.0-169/zeppelin/ (pointing to a non-existant folder)

When you follow the steps the Python scripts at some point do a 'yum install zeppelin' but in the meantime with things progressing it wil install version 2.4.2.0-258 WITHOUT updating the symlink properly. Besides that the scripted install is fine.

Tried to make the script install version 2.4.0.0-169 of Zeppelin but didn't succeed, so in the end al it took was updating the symlink:

ln -f -s /usr/hdp/2.4.2.0-258/zeppelin/ /usr/hdp/current/zeppelin-server

If you then rerun all from Ambari it should be fine and you'll have the newest Zeppelin installed.
