java - 动物园管理员启动错误:'JAVA_HOME error in zookeeper.out'

Question

当我这样做的时候

bin/zkServer.sh start    #It shows it has started

ZooKeeper JMX enabled by default
Using config: /data/sparkHA/zookeeper-3.4.9/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

几秒钟后，当我检查状态时，我得到了

ZooKeeper JMX enabled by default
Using config: /data/sparkHA/zookeeper-3.4.9/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.

我的zookeeper.out说

nohup: failed to run command â/usr/bin/java/bin/javaâ: Not a directory

但是我的bashrc中的JAVA_HOME是usr/bin/java，怎么多了一个/bin/java，导致目录无效。

还回显 $JAVA_HOME 输出

/usr/bin/java

如何处理此错误。请帮忙。谢谢。

还尝试通过以下方式在 zkServer.sh 中设置 JAVA_HOME Zookeeper not starting, nohup error但遇到同样的错误。

您的JAVA_HOME指向/usr/bin/java文件，但它应该指向您的JDK的根目录。例如对我来说这是:

➜  ~ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home
➜  ~ ll $JAVA_HOME
total 52064

因此，尝试设置 JDK 根目录的有效路径。我认为它应该可以解决您的问题。
