Hi @ssuja
In the above screenshot, we can see clearly, java path location is not able to find. Please verify and update the java path in nodes properly.

Hi @ssuja
Please try to run the SparkPi example and download the application logs. Once you are downloaded check is there any exceptions in the logs.
spark-submit \ --class org.apache.spark.examples.SparkPi \ --master yarn \ --deploy-mode cluster \ --num-executors 1 \ --driver-memory 512m \ --executor-memory 512m \ --executor-cores 1 \ /usr/hdp/current/spark2-client/examples/jars/spark-examples_*.jar 10

Hi @RangaReddy
Thank you for the reply.
We have four nodes HDP cluster, wherein recently java version upgraded only in three nodes.
In three nodes, we have upgraded the java path manually in the files Eg: spark-env.sh, yarn-env.sh, hadoop-env.sh .
We haven't upgraded the java path in one node where java version is not upgraded.
Executed the above mentioned command. Please find the attached screenshot of application logs.
Kindly help us.
