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 · Accepted solution]

This worked for me with Oozie HA with haproxy running OpenJDK 1.8.   I did have to make sure the three jars were unlinked on both oozie servers in the /opt/cloudera/parcels/CDH/lib/oozie/embedded-oozie-server/dependency/ directory.   Could it be possible that you may have these jars elsewhere in the classpath for oozie, maybe in the /var/lib/oozie directory?

unlink ./jetty-runner-9.3.20.v20170531.jar
unlink ./javax.servlet.jsp-api-2.3.1.jar
unlink ./javax.servlet.jsp-2.3.2.jar

Yes, I found the jar in other places, I remove the link, now the oozie web ui work fine! Thank you!

Now I try to fix the oozie ha problem.
