> The Tez UI can hang on task attempts listing and throw a "Type Error : link is undefined" when the link which is the variable that holds the logs link is null in cases where the task attempts were killed.
> The following check needs to be corrected to get past this error.
> {code}
>  link = attempt.get('completedLog');
>       if (link && yarnAppState === 'FINISHED' || yarnAppState === 'KILLED' || yarnAppState === 'FAILED') {
>         params["start"] = "0";
> {code}
