Subject [jira] [Commented] (AMBARI-7643) Jobs view: Input/Output bytes shows up as 0 for some jobs
Date Sat, 04 Oct 2014 02:04:33 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-7643?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14158868#comment-14158868

Alejandro Fernandez commented on AMBARI-7643:
---------------------------------------------

Turns out that in Ambari 1.7.0, the Ember javascript library was updated from 1.0-pre to 1.5.
In 1.0-pre, attempting to get a field that does not exist would return null, whereas in 1.5
it returns undefined (which cannot be added to another number, hence resulting in dispalying
0 even though hdfsReadBytes had a positive value).

screenshot), whereas it shows 0 bytes in 1.7.0 jobs view.
