             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.
