Hadoop - start-all.sh 未执行

Question

我今天更新到 Ubuntu 16.04，当我更新 start-all.sh 时，它会抛出这个：

This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
/usr/local/hadoop/bin/hdfs: line 304: /usr/lib/jvm/java-7-openjdk-amd64/bin/java: No such file or directory

JPS 仅显示4676 Jps。我已经安装了 mysql，它工作得很好。

你能帮忙吗？！

没关系，我解决了这个问题。我所要做的就是将/usr/local/hadoop/etc/hadoop/hadoop-env.sh 和bashrc 文件中的jdk 版本更改为java-8-openjdk-amd64。

感谢您的关注。
