JavaHiveContext inssue in spark - apache-spark

Question

I used
spark 1.2.1
hadoop 2.3.0-cdh5.0.2
hbase 0.96.1.1-cdh5.0.2
when I run spark app, it always show the below exception.
Actually I have
org.apache.hbase
hbase-protocol
And protobuf-java 2.5.0 has been build to spark assemble jar.
spark.SparkException: Job aborted due to stage failure: Task 0 in stage 0.0 failed 4 times, most recent failure: Lost task 0.3 in stage 0.0 (TID 3, cfswps1d-phys.nam.nsroot.net): java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/protobuf/generated/MasterProtos$MasterService$BlockingInterface

You will need to add the classes you are referencing in your program that are mentioned in the error: $MasterService$BlockingInterface to your Spark Conf File:
spark.driver.extraClassPath=
You can read more about the extraClassPath option on the spark site.
Note: In client mode, this config must not be set through the SparkConf directly in your application, because the driver JVM has already started at that point. Instead, please set this through the --driver-class-path command line option or in your default properties file.="whatever jar file directory or class files"
