Wangda Tan reassigned YARN-8141:
--------------------------------
Assignee: Chandni Singh
> YARN Native Service: Respect
> YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS specified in service spec
> ----------------------------------------------------------------------------------------------------------
>
> Key: YARN-8141
> URL: https://issues.apache.org/jira/browse/YARN-8141
> Project: Hadoop YARN
> Issue Type: Bug
> Components: yarn-native-services
> Reporter: Wangda Tan
> Assignee: Chandni Singh
> Priority: Critical
>
> Existing YARN native service overwrites
> YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS regardless if user
> specified this in service spec or not. It is important to allow user to mount
> local folders like /etc/passwd, etc.
> Following logic overwrites the
> YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS environment:
> {code:java}
> StringBuilder sb = new StringBuilder();
> for (Entry<String,String> mount : mountPaths.entrySet()) {
> if (sb.length() > 0) {
> sb.append(",");
> }
> sb.append(mount.getKey());
> sb.append(":");
> sb.append(mount.getValue());
> }
> env.put("YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS",
> sb.toString());{code}
> Inside AbstractLauncher.java
