[jira] [Commented] (TEZ-3504) Tez UI: Duration is displaying invalid values when start or end time is invalid

["Hitesh Shah (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TEZ-3504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15629887#comment-15629887 ] 

Hitesh Shah commented on TEZ-3504:
----------------------------------

Why is "undefined" being returned for the following case: endTime > 0 and startTime > 0 and startTime > endTime. This is a bug with respect to data and should likely be displayed as such to indicate that there is some incorrect data instead of showing Not available.

> The UI code must validate start - end times and calculate the duration only if their values are valid. If not valid a 'Not Available!' could be displayed.
> Following validations must be done:
> # Start time must be a number greater than 0
> # End time must be a number greater than 0
> # End time must be greater than or equal to start time
