Zhijie Shen commented on SAMZA-58:
----------------------------------
AMRMClientAsync can be used to talk to RM, and YarnAppMaster seems not to need
to do while loop to invoke allocate, and the following logic can be moved to
CallbackHandler's implementation. Similarly we can use NMClientAsync to replace
NMClient. I'd like to work on this issue.
> Use YARN's *Async API
> ---------------------
>
> Key: SAMZA-58
> URL: https://issues.apache.org/jira/browse/SAMZA-58
> Project: Samza
> Issue Type: Bug
> Components: yarn
> Affects Versions: 0.6.0
> Reporter: Chris Riccomini
>
> YARN 2.2.0 has a nice Async API for clients and AMs. This API didn't exist
> when we did the initial YARN integration for Samza. We should upgrade Samza
> to use these new APIs.
> The API is loosely based off Samza's own AM code, so we can probably strip
> out a lot of it (YarnAppMaster, mainly), and switch everything over to the
> call-back based API.
> For details, see:
> https://issues.apache.org/jira/browse/YARN-417
> This new API is used in DistributedShell now, so we can use that for testing.
