[jira] [Created] (YARN-1156) Change NodeManager AllocatedGB and AvailableGB metrics to show decimal values

Akira AJISAKA created YARN-1156:
-----------------------------------

             Summary: Change NodeManager AllocatedGB and AvailableGB metrics to show decimal values
                 Key: YARN-1156
                 URL: https://issues.apache.org/jira/browse/YARN-1156
             Project: Hadoop YARN
          Issue Type: Improvement
    Affects Versions: 2.1.0-beta
            Reporter: Akira AJISAKA
            Priority: Minor
             Fix For: 2.3.0


AllocatedGB and AvailableGB metrics are now integer type. If there are four times 500MB memory allocation to container, AllocatedGB is incremented four times by {{(int)500/1024}}, which means 0. That is, the memory size allocated is actually 2000MB, but the metrics shows 0GB. Let's use long type for these metrics.
