I'm using HDP2.6. where is installed oozie 4.2. and Spark2.
After I tracked Hortonworks guide on this site: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.1/bk_spark-component-guide/content/ch_oozie-spark-action.html for adding libs for Spark2 in 4.2. version of Oozie.
After I submit the job with this add-on:
oozie.action.sharelib.for.spark=spark2
The error I'm getting is this:

I have read that new Spark2 will not work with Spark 2.1 (via oozie anyway) due to a change in how Spark handles multiple files found in distributed cache, as mentioned here: see here
Keep in mind that I'm using Ambari and HDP2.6. How can I deal with this?
