Yufei Gu commented on YARN-7270: -------------------------------- The patch is straightforward. [~wangda]/[~templedf], could you take a look? > Resource#getVirtualCores() does unsafe casting from long to int. > ---------------------------------------------------------------- > > Key: YARN-7270 > URL: https://issues.apache.org/jira/browse/YARN-7270 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Affects Versions: 3.1.0 > Reporter: Yufei Gu > Assignee: Yufei Gu > Attachments: YARN-7270.001.patch > > > Class {{Resource}} has three sub classes(FixedValueResource, > LightWeightResource, and ResourcePBImpl). Only FixedValueResource handle > long-to-int casting nicely. The other two didn't. This bug is introduced by > resource type feature and causes several unit test failures.
