Steve Loughran updated YARN-4696:
---------------------------------
Attachment: YARN-4696-009.patch
This is the 009 patch; the difference with 008 is it is correctly converting
IllegalArgumentException to a BadRequestException with the nested stack trace.
With this patch applied with the current YARN-4545 patch, I now successfully
have
# all tests against completed jobs working with file://
# tests needing to track incomplete jobs working with an HDFS minicluster.
LocalFS isn't going to work as a destination for incomplete jobs, as it doesn't
flush(). Nor will things like S3. That'll need documenting
> 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.
