Chesnay Schepler updated FLINK-20973:
-------------------------------------
External issue URL: (was:
https://issues.apache.org/jira/browse/FLINK-17858)
> 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: Deployment / YARN
> Affects Versions: 1.10.1, 1.11.3
> Reporter: kunnni
> Priority: Major
>
> When I submitted flink-on-yarn job on Windows (Operating system of yarn
> cluster is Linux), I got error message: “Error: Could not find or load main
> class org.apache.flink.yarn.entrypoint.YarnJobClusterEntrypoint”.
> then I found out that 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.
> the solution is to 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());
> ......
> }{code}
