Subject [jira] [Commented] (YARN-710) Add to ser/deser methods to RecordFactory
Date Tue, 21 May 2013 18:51:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-710?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13663247#comment-13663247

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}

> 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.
