Whether support Spark on YARN, under the HDP in Kerberos environment?
I have 1 Mater +1 Worker
when I run
./bin/spark-submit –class org.apache.spark.examples.SparkPi –master yarn-cluster –num-executors 3 –driver-memory 512m –executor-memory 512m –executor-cores 1 lib/spark-examples*.jar 10

result is
