Unable to schedule job in oozie. Getting Error while creating HiveContext - apache-spark

Question

Trying to run a spark job from oozie. Below is the code which I am trying to run.
SparkConf conf = getConf(appName);
JavaSparkContext sc = new JavaSparkContext(conf);
HiveContext hiveContext = new HiveContext(sc);
I am getting the following error:
JOB[0000000-170808082825775-oozie-oozi-W] ACTION[0000000-170808082825775-oozie-oozi-W#Sample-node] Launcher exception: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
java.lang.RuntimeException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

Here's my workflow xml file

I am using Hortonworks Data Platform 2.5. Can any one please help if I am missing some thing in the classpath.
Thanks in advance.

Finally it worked. Oozie is able to create HiveContext.
Issue is with classpath. Delete the folder /user/oozie/share/lib in hdfs.
Update the following properties in Ambari under core-site.xml
Set the following properties to *
hadoop.proxyuser.oozie.groups
hadoop.proxyuser.oozie.hosts
hadoop.proxyuser.root.groups
hadoop.proxyuser.root.hosts
Created new shared library using the following command:
/usr/hdp/current/oozie-client/bin/oozie-setup.sh sharelib create -fs /user/oozie/share/lib
Restart oozie service
Above 2 steps should be done using oozie user
Added the following tags to work flow xml file
<spark-opts>--num-executors 6 --driver-memory 8g --executor-memory 6g</spark-opts>
Run the oozie job as hdfs user.
