----------------------------------
Summary: Add file handling features to the Windows Secure
Container Executor LRPC service
Key: YARN-2458
URL: https://issues.apache.org/jira/browse/YARN-2458
Project: Hadoop YARN
Issue Type: Sub-task
Components: nodemanager
Reporter: Remus Rusanu
Assignee: Remus Rusanu
In the WSCE design the nodemanager needs to do certain privileged operations
like change file ownership to arbitrary users or delete files owned by the task
container user after completion of the task. As we want to remove the
Administrator privilege requirement from the nodemanager service, we have to
move these operations into the privileged LRPC helper service.
Extend the RPC interface to contain methods for change file ownership and
manipulate files, add JNI client side and implement the server side. This will
piggyback on the existing LRPC service so is not much infrastructure to add
(run as service, RPC init, authentictaion and authorization are already
solved). It just needs to be implemented.
