------------------------------------
Summary: Allow container-executor to use private /tmp
Key: YARN-5352
URL: https://issues.apache.org/jira/browse/YARN-5352
Project: Hadoop YARN
Issue Type: Improvement
Components: nodemanager
Reporter: Nathan Roberts
Assignee: Nathan Roberts
It's very common for user code to create things in /tmp. Yes, applications have
means to specify alternate tmp directories but doing so is opt-in and therefore
doesn't happen in many case. At a minimum, linux can use private namespaces to
create a private /tmp for each container so that it's using the same space
allocated to containers and it's automatically cleaned up as part of container
clean-up.
