> 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.
