--------------------------------
Summary: [Umbrella] Revisit YARN ProtocolBuffer int32 usages that
need to upgrade to int64
Key: YARN-4843
URL: https://issues.apache.org/jira/browse/YARN-4843
Project: Hadoop YARN
Issue Type: Bug
Components: api
Reporter: Wangda Tan
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.
