java - 启动flume agent显示jdk路径错误，是目录，无法执行

Question

我在安装 flume 时遇到错误。 由于 jdk 路径显示为目录且无法执行，我无法启动 flume agent。 请帮我解决这个问题，以便在我的 hdfs

中获取 JSON 数据

bin/flume-ng: line 241: exec: /usr/lib/java/jdk1.8.0_131: cannot execute: Is a directory

Answer 1

flume-ng 代理 使用的java 路径 格式不正确。
错误似乎在 + exec/usr/lib/java/jdk1.8.0_131 bin/java 中，应该是 + exec/usr/lib/java/jdk1.8.0_131/bin/java 中间没有空格

应该是以下之一

1 你在某处设置了错误的 JAVA_HOME (.bashrc 或 flume-env.sh 或 ...)

2 flume-ng 格式错误并使用格式错误的 java 路径。

所以你必须纠正其中的任何两个。从我与您的沟通来看，您的 java 路径似乎不错。

因此您必须下载最新的 Flume 并查看问题是否解决。
谢谢
