Sidharta Seethana updated YARN-3684:
------------------------------------
Description: As per description in parent JIRA : Adding additional
arguments to key ContainerExecutor methods ( e.g startLocalizer or
launchContainer ) would break the existing ContainerExecutor interface and
would require changes to all executor implementations in YARN. In order to make
this interface less brittle in the future, it would make sense to encapsulate
arguments in some kind of a ‘context’ object which could be modified/extended
without breaking the ContainerExecutor interface in the future.
> Change ContainerExecutor's primary lifecycle methods to use a more extensible
> mechanism for passing information.
