Problem:
[[email protected] ~]# start-slaves.sh slave1: starting org.apache.spark.deploy.worker.Worker, logging to /usr/local/spark-1.6.3-bin-hadoop2.6/logs/spark-root-org.apache.spark.deploy.worker.Worker-1-slave1.out slave2: starting org.apache.spark.deploy.worker.Worker, logging to /usr/local/spark-1.6.3-bin-hadoop2.6/logs/spark-root-org.apache.spark.deploy.worker.Worker-1-slave2.out slave2: failed to launch org.apache.spark.deploy.worker.Worker: slave1: failed to launch org.apache.spark.deploy.worker.Worker: slave1: JAVA_HOME is not set slave1: full log in /usr/local/spark-1.6.3-bin-hadoop2.6/logs/spark-root-org.apache.spark.deploy.worker.Worker-1-slave1.out slave2: JAVA_HOME is not set slave2: full log in /usr/local/spark-1.6.3-bin-hadoop2.6/logs/spark-root-org.apache.spark.deploy.worker.Worker-1-slave2.out
Solve:
切入對應的slave的spark根目錄，在sbin目錄下的spark-config.sh 中新增對應的jdk路徑！
##我的spark根目錄spark-1.6.3-bin-hadoop2.6
cd /usr/local/spark-1.6.3-bin-hadoop2.6/sbin
vi spark-config.sh
## JAVA 新增java_home路徑
export JAVA_HOME=/usr/local/jdk1.8
export PATH=$PATH:$JAVA_HOME/bin
