Carlo Curino commented on YARN-5124:
------------------------------------
[~asuresh] this seems better, however you still have the typedefs in the new
class, and you have foreach loops on Object that are a bit weird. Would it be
possible to move into the {{RemoteRequestTable}} the {{addResourceRequest}},
{{decResourceRequest}} and {{getMatchingRequests}}. This could simplify further
the {{AMRMClientImpl}} and delegate to the db-style class all matter of data
access.
Concretely I propose:
1) get rid of the typedefs
2) move the add/dec/get to the RemoteRequestTable
3) create a new getter to support {{checkLocalityRelaxationConflict}} where the
matching is done internally in {{RemoteRequestTable}} and the external method
operates on a narrowly typed list (built by the getter).
This would fully encapsulate the data storage/access and allow you to evolve
that independently of the external business-logic classes.
