>
> The download link when pointing to the in-progress URL will not work in most
> cases as the downloaded page is the link to the NM which internally redirects
> to the job history. This means that the downloaded file will not have any
> actual log contents.
> Possible solutions:
> - only show download button when an application has completed. Please note
> that this is for when a yarn app has completed. A completed DAG has no
> guarantee that its logs are available for download.
> - download link should always only rely on completed log url and never on
> in-progress url
> - view logs link can always point to in-progress url as it will
> automatically redirect to the jobhistory logs url if the container has
> completed.
