>             Project: Hadoop YARN

> This JIRA is to track all int32 usages in YARN's ProtocolBuffer APIs that we possibly
need to update to int64.
> One example is resource API. We use int32 for memory now, if a cluster has 10k nodes,
each node has 210G memory, we will get a negative total cluster memory.
> We may have other fields may need to upgrade from int32 to int64.
