Subject [jira] [Commented] (YARN-710) Add to ser/deser methods to RecordFactory
Date Wed, 22 May 2013 18:27:23 GMT

    [ https://issues.apache.org/jira/browse/YARN-710?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13664384#comment-13664384
] 

Siddharth Seth commented on YARN-710:
-------------------------------------

bq. Regardless of that, the ser/deser mechanism provided in this patch should do the real
work for all records. Then it is matter of deciding for which ones we want to expose the ser/deser
capabilities proxying to record factory implementation, right?
Agreed. This can be the internal (private) implementation for whatever the public utility
is that exposes ser/deser for various records. The internal implementation could then be used
by RMStateStore as well.

> I order to do things like AMs failover and checkpointing I need to serialize app IDs,
app attempt IDs, containers and/or IDs,  resource requests, etc.
> Because we are wrapping/hiding the PB implementation from the APIs, we are hiding the
built in PB ser/deser capabilities.
