Sergey Shelukhin commented on TEZ-3906:
---------------------------------------
cc [~hagleitn] [~ewohlstadter] this will be needed to expand AM recovery in
Hive beyond LLAP-using AMs. Currently there's no way to host AM registry in the
AM otherwise (that I know of)
> general purpose plugin interface

> Key: TEZ-3906
> URL: https://issues.apache.org/jira/browse/TEZ-3906
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Sergey Shelukhin
> Assignee: Eric Wohlstadter
> Priority: Major
>
> Tez has plugin interfaces for communicator, scheduler, and stuff.
> It would be nice to be able to host general purpose code in Tez AM for
> particular purposes.
> E.g. currently Hive AM registry (that may contain some Hive-specific stuff
> that is neither appropriate, nor convenient w.r.t. compat and flexibility
> when it's changed, for Tez codebase) is hosted via LLAP plugin, which limits
> its applicability.
> It would be nice to be able to add one or several general purpose plugins
> with start/stop interface.
