> description: When I submitted flink-on-yarn job on Windows (Operating system 
> of yarn cluster is Linux), I got error message: 
> {panel}
> Error: Could not find or load main class 
> org.apache.flink.yarn.entrypoint.YarnJobClusterEntrypoint
> {panel}
> cause: Windows has different *classPath delimiter* with Linux as in Windows 
> is " *;* ", but in Linux is " *:* ".  the main cause is that classPath was 
> built on Windows, but was splitted on Linux. 
> solution : replace value of  *File.pathSeparator* with 
> *ApplicationConstants.CLASS_PATH_SEPARATOR* in class of 
> org.apache.flink.yarn.YarnClusterDescriptor and org.apache.flink.yarn.Utils.
>  
> sourceCode is displayed below:
> {code:java}
> private ApplicationReport startAppMaster(......) throws Exception {
>  ......
>  // classpath assembler
>  StringBuilder classPathBuilder = new StringBuilder();
>  if (userJarInclusion == YarnConfigOptions.UserJarInclusion.FIRST) {
>  for (String userClassPath : userClassPaths)
> { classPathBuilder.append(userClassPath).append(File.pathSeparator); }
> }
>  for (String classPath : systemClassPaths)
> { classPathBuilder.append(classPath).append(File.pathSeparator); }
> ......
>  // Setup CLASSPATH and environment variables for ApplicationMaster
>  final Map<String, String> appMasterEnv = new HashMap<>();
>  // set user specified app master environment variables
>  appMasterEnv.putAll(
>  
> BootstrapTools.getEnvironmentVariables(ResourceManagerOptions.CONTAINERIZED_MASTER_ENV_PREFIX,
>  configuration));
>  // set Flink app class path
>  appMasterEnv.put(YarnConfigKeys.ENV_FLINK_CLASSPATH, 
> classPathBuilder.toString());
