---------------------------------
Assignee: Adam Antal
> Add ability for ATS (log servlet) to read logs of running apps
> --------------------------------------------------------------
>
> Key: YARN-10027
> URL: https://issues.apache.org/jira/browse/YARN-10027
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Adam Antal
> Assignee: Adam Antal
> Priority: Minor
>
> 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.
