Oozie web GUI when downgrading from CDH5.12.0 to CDH5.5.4

[#1]

Hi,

I'm testing my cluster upgrade from cdh5.5.4 to CDH5.12.0

when i tried to downgrade the cdh the oozie web UI isn't accessible, the job scheduling is working and it's just the oozie web UI

org.apache.jasper.JasperException: Unable to compile class for JSP:

The type java.io.ObjectInputStream cannot be resolved. It is indirectly referenced from required .class files

The downgrade is perhaps referencing newly compiled files from the 5.12 run.

With the Oozie server stopped, perhaps try clearing out all 'oozie' owned directories/files under /tmp on the Oozie server. Also try a fresh /var/lib/oozie/ directory (with just dependent jars you require present, but no other existing dirs under it).

@Harsh J Tried the suggested with no success

Deleted all files with oozie regex under /tmp/ and removed the tomcat deployment from /var/lib/oozie and what left under the dir is the mysql connector and the xt2.2 folder
