Jonathan Hung commented on YARN-5946:
-------------------------------------
Attached 002 patch. {{initialize}}, {{retrieve}}, and {{store}} are for
retrieving/storing the configuration. {{readPersistedId}}, {{getMutations}},
and {{logMutations}} are for write ahead logging which implementations should
support. This delegates the recovery part of write ahead logging to the calling
class, in this case {{MutableConfigurationManager}}. This is necessary because
the store does not know whether a logged configuration change is valid or not.
If the calling class determines the logged mutations are valid, it can
{{store}} them.
