Wangda Tan created YARN-8141:
--------------------------------
Summary: 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
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
