This page gives a list of common errors you may experience with ZooKeeper on Windows.

C:\programs\zookeeper>bin\zkServer.cmd The system cannot find the path specified. Error: JAVA_HOME is incorrectly set. C:\programs\zookeeper>call ... org.apache.zookeeper.server.quorum.QuorumPeerMain "C:\programs\zookeeper\bin\..\conf\zoo.cfg" The filename, directory name, or volume label syntax is incorrect. C:\programs\zookeeper>endlocal
How to fix this error:
► You have to double-quote the path "%JAVA_HOME%\bin\java.exe" in the file "%ZK_ROOT%\bin\zkEnv.cmd"

C:\programs\zookeeper>bin\zkServer.cmd C:\programs\zookeeper>call ... org.apache.zookeeper.server.quorum.QuorumPeerMain "C:\programs\zookeeper\bin\..\conf\zoo.cfg" 'C:\Program' is not recognized as an internal or external command, operable program or batch file. C:\programs\zookeeper>endlocal

• How to fix this error - Solution (1):
  ► You have to double-quote the path "%JAVA%" in the file "%ZK_ROOT%\bin\zkServer.cmd"
  
  
• How to fix this error - Solution (2):
  ► Copy and rename the file "%ZK_ROOT%\conf\zoo_sample.cfg" to "%ZK_ROOT%\conf\zoo.cfg"

How to fix this error:
► You have to create the directory that is defined by the property "dataDir" in the file "%ZK_ROOT%\conf\zoo.cfg".

► You have to add a "myid" file to this directory ("dataDir").

► You have also to create the directory that is defined by the property "dataLogDir" in the file "%ZK_ROOT%\conf\zoo.cfg".

• How to fix this error - Solution (1):
  
  ► file "%ZK_ROOT%\conf\zoo.cfg": delete this line
  dynamicConfigFile=./conf/zoo.cfg.dynamic.100000000
  ► file "%ZK_ROOT%\conf\zoo.cfg": add the server(s) static configuration
  server.1=localhost:2888:3888
  ► You can delete the file "%ZK_ROOT%\conf\zoo.cfg.dynamic.100000000"
  
  
• How to fix this error - Solution (2):
  
  I had to change the config in the file "%ZK_ROOT%\conf\zoo.cfg"
  
  Current config:
  dynamicConfigFile=C:\programs\zookeeper\conf\zoo.cfg.dynamic.100000000
  Replaced with:
  dynamicConfigFile=./conf/zoo.cfg.dynamic.100000000
  
• How to fix this error - Solution (3):
  
  I had to change the config in the file "%ZK_ROOT%\conf\zoo.cfg"
  
  Current config:
  dynamicConfigFile=C:\programs\zookeeper\conf\zoo.cfg.dynamic.100000000
  Replaced with:
  dynamicConfigFile=C\:/programs/zookeeper/conf/zoo.cfg.dynamic.100000000

How to fix this error:
The default port is 8080 for the Jetty enbeded server.

► use the property "admin.serverPort" in the "zoo.cfg" file to set a different port: "admin.serverPort=8081"

► or, modify the "zkServer.cmd" file and use the java system property "zookeeper.admin.serverPort" to override the default value.
call "%JAVA%" "-Dzookeeper.admin.serverPort=8081" ...
