Dear Experts,
I'm running a small YARN cluster configured to use simple security,
LinuxContainerExecutor and
yarn.nodemanager.linux-container-executor.nonsecure-mode.limit-users=false
in order to get correct uid when executing jobs. This is needed to
access files from network exported filesystem.
I was wondering - does this posses any security risk (since
nonsecure-mode.limit is set to true by default in the simple security
mode)? I.e. is there a known way for a user to get uid of different user
with such configuration?
Cheers,
Tomasz
