[jira] [Commented] (REEF-906) Split DriverInfo and ReefServicesInfo and move certain avsc files into reef-common

["Andrew Chung (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/REEF-906?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14990856#comment-14990856 ] 

Andrew Chung commented on REEF-906:
-----------------------------------

I'm assuming REEF endpoints will need a mechanism of deprecation if this were to go through. [~markus.weimer] [~MariiaMykhailova] what is the recommended protocol? I don't think it will be visible if we deprecate the endpoints within our codebase by using the Deprecate annotation.

> In order to make {{HeartbeatManager}} in the Evaluator aware of how to deserialize Avro passed back by the Driver, it needs to know how to deserialize {{DriverInfo}}, but currently {{DriverInfo}} is tied in the webserver project, which common has no dependency on. This proposes to:
> 1. Move {{DriverInfo}}, {{EvaluatorInfo}}, {{EvaluatorList}} into reef-common, which is reasonable because they can serve more purpose beyond {{reef-webserver}}
> 2. Split {{DriverInfo}} and {{ReefServicesInfo}}
> 3. Provide a new /services endpoint for services info instead of using the /driver endpoint for both
