> int64
> ---------------------------------------------------------------------------------

> Key: YARN-4843
> URL: https://issues.apache.org/jira/browse/YARN-4843
> Project: Hadoop YARN
> Issue Type: Bug
> Components: api
> Affects Versions: 3.0.0-alpha1
> Reporter: Wangda Tan
> Priority: Major
>
> 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.
