Alejandro Abdelnur commented on YARN-710:
-----------------------------------------
Per discussion in the yarn-dev@,
http://mail-archives.apache.org/mod_mbox/hadoop-yarn-dev/201305.mbox/browser ,
as per Bobby suggestion, a simple way to do this would be something along the
following lines:
{code}
public interface RecordFactory {
public <T> T newRecordInstance(Class<T> clazz) throws YarnException;
public <T> T newRecordInstance(Class<T> clazz, byte[] data) throws
YarnException;
public <T> byte[] fromRecordInstance(T t) throws YarnException;
}
{code}
> Add to ser/deser methods to RecordFactory

> 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.
