Subject [jira] [Commented] (YARN-7694) Optionally run shared cache manager as part of the resource manager
Date Tue, 02 Jan 2018 22:48:00 GMT

Miklos Szegedi commented on YARN-7694:
--------------------------------------

[~ctrezzo], thank you for raising this. The shared cache manager could extend its features,
when running as part of resource manager. It might be useful to register any HDFS file for
deletion, if not used for a while, even if they are not part of the shared cache with the
same codebase. What do you think?

> Currently the shared cache manager is its own stand-alone daemon. It is a YARN composite
service. Ideally, the shared cache manager could optionally be run as part of the resource
manager. This way administrators would have to manage one less daemon.
