Steve Loughran updated YARN-4696:
---------------------------------
Attachment: YARN-4696-012.patch
Patch 012. This is what I've been successfully using in tests —giving up trying
to have incomplete apps if the FS is LocalFileSystem, and instead using an
MiniHDFSCluster for those test cases. The tests all work.
This is ready for review and ideally, getting into 2.8
> EntityGroupFSTimelineStore to work in the absence of an RM

> {{EntityGroupFSTimelineStore}} now depends on an RM being up and running; the
> configuration pointing to it. This is a new change, and impacts testing where
> you have historically been able to test without an RM running.
> The sole purpose of the probe is to automatically determine if an app is
> running; it falls back to "unknown" if not. If the RM connection was
> optional, the "unknown" codepath could be called directly, relying on age of
> file as a metric of completion
> Options
> # add a flag to disable RM connect
> # skip automatically if RM not defined/set to 0.0.0.0
> # disable retries on yarn client IPC; if it fails, tag app as unknown.
