Xuan Gong commented on YARN-4920:
---------------------------------

Create a new web service in AHS web service.
{code}
use 
ats_host:atsport/ws/v1/applicationhistory/containerlogs/{containerid}/{filename}
to show the container logs in ui

use
ats_host:atsport/ws/v1/applicationhistory/containerlogs/{containerid}/{filename}?download=true
to download the container logs 
{code}

For the running application, it will redirect the request to the related NM. For the finished apps, it will parse and download logs from hdfs
