Error starting zookeeper using bash on Windows 10

[THADC <ti...@gmail.com>]

Hello,

I am not sure whether my problem has anything to do with bash exactly, but I
am trying to run zookeeper server (3.4.10) for the first time. By the way, I
did search for this in archive but could not find a match that worked for
me.

When I started it in foreground mode, I get the following:

*$ ./bin/zkServer.sh start-foreground
ZooKeeper JMX enabled by default
Using config:
/c/DevelopmentTools/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg
Error: Could not find or load main class
org.apache.zookeeper.server.quorum.QuorumPeerMain*

, that class is in the zookeeper-3.4.10.jar, which is directly in the
zookeeper-3.4.10 root directory. I added that directory to my classpath:

*$ echo $CLASSPATH
C:\Program Files\Java\jdk1.8.0_112\bin;C:\Program
Files\Java\jre1.8.0_112\bin;C:\DevelopmentTools\zookeeper\zookeeper-3.4.10*

, so as you can see above, the directory is in the classpath, but I am still
getting the error. Any ideas what my problem is? 

Thank you!

Hi THADC,

Is this a Windows 10 linux subsystem session?

Hi,

The zkServer.sh sets the classpath itself (with -cp, but including
CLASSPATH variable). You don't need to set it manually.
But if that doesn't work, for jar file, you have to include the .jar file.
So it is not enough to set the directory where the .jar file is, you have
to specify the .jar file. i.e.:
C:\DevelopmentTools\zookeeper\zookeeper-3.4.10\zookeeper.jar

Let me know if it is still not working. You can try to print the classpath
with echo to see if the .jar file is included (or the root package).

By the way, if you are using linux bash, I would also try to use forward
slash, as backslash tend to be problematic sometimes.

Hope this helps.

Regards,
Norbert
