Cannot access to Oozie Web UI with Error message below

[#1]

Hi,

I just installed the CDH 6.1 on my VMs, and I've tried to access to oozie web ui.

But I failed with the message below.

I've tried to set java home with exact location and reinstall the jdk files, but both didn't work. 

[#2 · Accepted solution]

I solved this problem by installing openjdk-1.8.0 using yum and settnig java classpath.

[#3]

Hi,

We have seen this with a few upgrades to CDH 6.X from CDH 5.X recently.   Could you please confirm if this was an upgrade (you had mentioned "just installed", so we would like to confirm)?   The solution for upgrades has been to:

1. Execute the below command on the Oozie server host command line
unlink /opt/cloudera/parcels/CDH-6.1.0-1.cdh6.1.0.p0.770702/lib/oozie/embedded-oozie-server/dependency/javax.servlet.jsp-2.3.2.jar

*note that we aim to only remove the link to the actual jar file

2.  Restart Oozie server
3.  Please check if the web ui comes up correctly.

This should be fixed in a future upgrade.

Thanks,

Robert Justice

[#4]

Thank you for your reply.

No, I've just installed CDH 6.1 using cloudera-manager-installer.bin.

After the CDH 6.1 cluster has been set, I follow the instruction below to enable the oozie web UI but failed.

[#6]

Our CDH6.1 cluster is a fresh installation, not an upgrade, and also has the problem. I had tried your solution, canceled the unlink, but still failed . How to deal with this problem for a fresh installation of CDH cluster?

[#7]

I confirmed this problem definitely does occur, even with fresh install.   Removing the link to javax.servlet.jsp-2.3.2.jar in the/opt/cloudera/parcels/CDH/lib/oozie/embedded-oozie-server/dependency directory, and restarting, does solve it in my test environment.  The below is for the latest - CDH 6.1.1.   We will be resolving this in the CDH 6.2 release.   Could you please confirm the link is gone, on the oozie server, and confirm the oozie server was restarted?

and then I restarted the oozie server ,

then I still can't open the oozie web ui, with the error:

My apologies as there were two additional jars in the final bugfix that I missed in my original suggestion.   Could you please also do the following in the /opt/cloudera/parcels/CDH/lib/oozie/embedded-oozie-server/dependency directory:

unlink ./jetty-runner-9.3.20.v20170531.jar

unlink ./javax.servlet.jsp-api-2.3.1.jar

Restart the oozie server, and please let me know if your oozie web console then functioning.

[#10]

I tried your solution, unlink the three jars of all hosts of my cluster, and then restarted the oozie server, but still didn't work, the dependency of oozie directory now is :

My cluster is CDH6.1.0,  JDK8 of Oracle Version. 

And another problem I found is that the HA of oozie with haproxy cannot be setted in CDH6.1.0. I will post this problem in another post.

[#11]

Interesting.   I'll make sure I test on HA with OpenJDK.   Just to be sure as you mentioned HA, you did this unlink on all oozie servers behine your haproxy instance, correct?
