zookeeper Starting error :'JAVA_HOME error in zookeeper.out'

Question

When I do

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

Afetr few second when i check status, I got

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.

My zookeeper.out says

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

But my JAVA_HOME in bashrc is usr/bin/java, How come one extra /bin/java is added , that results in an invalid directory.

Also echo $JAVA_HOME outputs

/usr/bin/java

How to approach this error. Please Help. Thanks.

Also tried setting JAVA_HOME in zkServer.sh also by following Zookeeper not starting, nohup error but getting same error.

Your JAVA_HOME point to /usr/bin/java file but it should point to root directory of your JDK. For example for me this is:

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

So, try to set valid path to JDK root directory. I think it should fix your problem.
