Adam Antal updated YARN-10027:
------------------------------
Description:
Currently neither version of the AHS is able to read logs of running apps
(local logs of NodeManager). YARN log CLI is integrated with NodeManager to
extract local logs as well (see YARN-5224 for reference), the same should be
done for ATS.
Some context:
The local log files are read by the server in
{{NMWebServices#getContainerLogFile}}. This is accessed by the YARN logs CLI
through REST using the /containers/\{containerid}/logs/\{filename} endpoint in
{{LogsCLI#getResponeFromNMWebService}}.
If YARN-10026 we can pull the common code pieces out of those services, we can
implement this in the common log servlet.
