localhost: JAVA_HOME is not set

localhost: starting org.apache.spark.deploy.worker.Worker, logging to /usr/local/cluster/spark-2.3.2-bin-hadoop2.7/logs
localhost: failed to launch: nice -n 0 /usr/local/cluster/spark-2.3.2-bin-hadoop2.7/bin/spark-class org.apache.spark.de
localhost:   JAVA_HOME is not set

왜일까..?

/etc/profile에 있던 java_home을 ~/.bashrc로 했더니 위에 해당 문구가 사라졌다^_^
