[jira] [Created] (AMBARI-23309) YARN cluster memory graph is not loading in Ambari 2.6

Andrii Tkach created AMBARI-23309:
-------------------------------------

             Summary: YARN cluster memory graph is not loading in Ambari 2.6
                 Key: AMBARI-23309
                 URL: https://issues.apache.org/jira/browse/AMBARI-23309
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.6.2
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
             Fix For: 2.7.0


Users are not able to see cluster memory graph under YARN. This was working before upgrade.

We were able to reproduce this internally on Ambari 2.6. We checked across 5 clusters and all of them exhibited same behaviour.

Seems like problem with the compute : mem_total._sum - mem_free._sum fails but mem_total._sum + mem_free._sum succeeds.

Also if we load mem_total._sum AND mem_free._sum individually, they come up fine.

Seems like issue when we do a 'subtract'.
