Question

今天我更新到Ubuntu 16.04，当我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
Starting namenodes on []
localhost: starting namenode, logging to /usr/local/hadoop/logs/hadoop-hduser-namenode-nkhl.out

localhost: /usr/local/hadoop/bin/yarn: line 333: /usr/lib/jvm/java-7-openjdk-amd64/bin/java: No such file or directory

JPS仅显示4676 Jps。我安装了mysql，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。

感谢您的回顾。

Hadoop - start-all.sh没有执行
