Container exited with a non-zero exit code 127

先去http://localhost:8088/cluster上查看失败日志

发现找不到/bin/java

修改yarn-env.sh

24 if [ "$JAVA_HOME" != "" ]; then
 25   #echo "run java in $JAVA_HOME"
 26   JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home
 27 fi
 28 
 29 if [ "$JAVA_HOME" = "" ]; then
 30   echo "Error: JAVA_HOME is not set."
 31   exit 1
 32 fi
 33 
 34 JAVA=$JAVA_HOME/bin/java

改第26行 JAVA_HOME就可以了 原来默认是$JAVA_HOME
第34行没有读到

参考文章:http://blog.csdn.net/lihe2008125/article/details/44901791

他让我去/bin/下面创建一个java 软连接，我没权限，所以只能另辟蹊径了。
