Passing hbase-site.xml to spark jobs using spark.driver.extraLibraryPath

I am running Cloudera Express 5.12.1 with CDH-5.12.1.

I need to read/write data from HBase from my Spark jobs.

I set thefollowing settings:



In CM "Spark Client Advanced Configuration Snippet (Safety Valve) for spark-conf/spark-defaults.conf." in the Spark Service.  I can see my values being written in /etc/spark/conf/spark-defaults.conf  correctly.

Now I submit a Spark job (part of Oozie workflow).  I expect that the hbase config is picked up from the class path, but it is not.  I can see the correct setting in the Spark Histroy Server for the job:


spark.driver.extraLibraryPath	/etc/hbase/conf/hbase-site.xml:/var/cloudera/parcels/CDH-5.12.1-1.cdh5.12.1.p0.3/lib/hadoop/lib/native

but the connection to the Zookeeper is not honoring the host that is specified in the hbase.zookeeper.quorum setting from the hbase-site.xml file, but is trying to connect to localhost.


I wish I can specify the hbase-site.xml globally, and not for each of the Spark jobs, as I have many, so my intention is to confgure this globally.   What am I doing wrong?  What is the best practice to follow in this case?
