Subject [jira] [Commented] (YARN-841) Annotate and document AuxService APIs
Date Tue, 18 Jun 2013 00:55:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-841?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13686256#comment-13686256

Hitesh Shah commented on YARN-841:

Definitely more helpful to application developers now. 

Some minor unrelated comments:

- ContainerStartResponse#getAllServicesMetaData probably belongs into an additional api to
query directly from the NM without needing to launch a container. Separate jira?
- 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

> 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.
