Subject [jira] [Commented] (YARN-841) Annotate and document AuxService APIs
Date Tue, 18 Jun 2013 00:59:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-841?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13686261#comment-13686261

Vinod Kumar Vavilapalli commented on YARN-841:

bq. ContainerStartResponse#getAllServicesMetaData probably belongs into an additional api
to query directly from the NM without needing to launch a container. Separate jira?
Yes: YARN-785. But it's a big API change :(

bq. Map<String, ByteBuffer> getAllServicesMetaData - Probably does not matter as the
NM cannot support 2 versions of the same service. In any case, we should file jira to address
discovery of services, what versions they are running so that the meta data can be correctly
Agreed. Will do.

> For users writing their own AuxServices, these APIs should be annotated and need better
documentation. Also, the classes may need to move out of the NodeManager.
