I am trying to execute a Spark application built through Scala IDE through my standalone Spark service running on cloudera quickstart VM 5.3.0.
My cloudera account JAVA_HOME is /usr/java/default
However, I am facing the below error message while executing the start-all.sh command from cloudera user as below:
[cloudera@localhost sbin]$ pwd

I had added export CMF_AGENT_JAVA_HOME=/usr/java/default in /etc/default/cloudera-scm-agent and run sudo service cloudera-scm-agent restart. See How to set CMF_AGENT_JAVA_HOME
I had also added export JAVA_HOME=/usr/java/default in locate_java_home function definition in file /usr/share/cmf/bin/cmf-server and restarted the cluster and standalone Spark service
But the below error is repeating while starting spark service from root user
[root@localhost spark]# sbin/start-all.sh

Can anybody suggest how to set JAVA_HOME so as to start Spark standalone service on cloudera manager?
The solution had been quite easy and straightforward. Just added export JAVA_HOME=/usr/java/default in /root/.bashrc and it successfully started the spark services from root user without the JAVA_HOME is not set error. Hope it helps somebody facing same problem.
