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.
