spark 1.2 + Avro does not work

have recently installed HDP2.2(Depends on hadoop 2.6).
My spark 1.2 is built with hadoop 2.3 profile.
( mvn -Pyarn -Dhadoop.version=2.6.0 -Dyarn.version=2.6.0 -Phadoop-2.3 -Phive -DskipTests clean package)

My program has following dependencies
val avro = “org.apache.avro” % “avro-mapred” %”1.7.7″
val spark = “org.apache.spark” % “spark-core_2.10″ % “1.2.0” % “provided”

My program to read avro files fails with the following error. What am I doing wrong?

Thanks
Manas
