> failed to submit flink-on-yarn job on Windows due to error of classPath

> Key: FLINK-20973
> URL: https://issues.apache.org/jira/browse/FLINK-20973
> Project: Flink
> Issue Type: Bug
> Components: Client / Job Submission, Deployment / YARN
> Affects Versions: 1.10.1, 1.11.3
> Reporter: kunnni
> Priority: Minor
>
> 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());
> ......
