----------------------------------------
Summary: EU: Modify configs to enable custom extensions
functionality
Key: AMBARI-21610
URL: https://issues.apache.org/jira/browse/AMBARI-21610
Project: Ambari
Issue Type: Task
Affects Versions: 2.5.2
Reporter: Siddharth Wagle
Assignee: Siddharth Wagle
Priority: Critical
Fix For: 2.5.2
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
