> We need EU to modify the configs that we have changed to add the path to the
> class path.
> *Pre Upgrade* (say for hadoop in a BI-4.2.5 cluster)
> * There is an HDFS folder /iop/ext/4.2.5/hadoop where users have put their
> custom extension jars
> * On start of hadoop services we copy jars from HDFS to on disk location
> {{/usr/iop/current/ext/hadoop}}
> * All class path variables include the on disk path
> *Post Upgrade* (for HDP-2.6.2 cluster)
> * HDP clusters now have an HDFS folder /hdp/ext/2.6/hadoop where the users
> must copy the extension jars again (some jars may be new as its an upgrade)
> * On start of hadoop services we copy jars from the above location to disk at
> /usr/hdp/current/ext/hadoop
> * Class paths now should now have the above path
