I ran the release spark in cdh5.3.0 but got the same error. Anyone tried to
run spark in cdh5.3.0 using its newAPIHadoopRDD?
command:
spark-submit --master spark://master:7077 --jars
/opt/cloudera/parcels/CDH-5.3.0-1.cdh5.3.0.p0.30/jars/spark-examples-1.2.0-cdh5.3.0-hadoop2.5.0-cdh5.3.0.jar
./sparkhbase.py
Error.
