----------------------------------
Summary: Giraph on YARN will need a WebUI to display job stats,
Yammer metrics, whatever
Key: GIRAPH-568
URL: https://issues.apache.org/jira/browse/GIRAPH-568
Project: Giraph
Issue Type: Improvement
Affects Versions: 0.2.0
Reporter: Eli Reisman
Fix For: 0.2.0
In YARN, the Client is the driver program when you run a job at the commmand
line. This lauches the application master, which is like an uber-master that
manages the job lifecycle for all the Giraph worker/master tasks that actually
run the BSP job.
The Application Master can register an RPC Port and a Tracking URL with the
YARN system (ResourceManager) which will be published on the YARN cluster WebUI
in case folks running a Giraph job want to see detailed formatted web info such
as Hadoop has. Previously we have hijacked Hadoop's counters and web ui. Now,
we can start to think fresh about how to read logs, view job and node status,
memory use, disk spills, Yammer metrics, whatever.
Someone could get very creative with this. If someone is feeling up to it, I
can show you where the YARN bits are you will want to interface with. The rest
can really go any way you want it to.
