1) Having figured out the error the fix would be to put the right version
of avro libs into AM JVM classpath. Hence i included --jars
/home/dvasthimal/spark/avro-mapred-1.7.7-hadoop2.jar,/home/dvasthimal/spark/avro-1.7.7.jar
in spark-submit command. However i still see the same exception.
2) I tried to include these libs in SPARK_CLASSPATH. However i see the same
exception.
