Hadoop - start-all.sh 未執行

Question

我今天更新到 Ubuntu 16.04，當我執行start-all.sh ，它會拋出這個：

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
Starting namenodes on []

JPS 僅顯示4676 Jps 。 我已經安裝了 mysql，它工作得很好。

你能幫忙嗎？！

沒關系，我解決了這個問題。 我所要做的就是將/usr/local/hadoop/etc/hadoop/hadoop-env.sh和bashrc文件中的 jdk 版本更改為java-8-openjdk-amd64 。

不過還是謝謝你看。
