Bikas Saha commented on TEZ-1626:
---------------------------------
Separate logs are generated at the AM per DAG and named syslog_dag_xyz.
These separate per dag logs are available from the YARN web UI for download
from the logs link on the AM page.

> Key: TEZ-1626
> URL: https://issues.apache.org/jira/browse/TEZ-1626
> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.5.0
> Reporter: Mostafa Mokhtar
> Labels: tez
> Fix For: 0.6.0
>
>
> When a user submits multiple Hive queries using the same connection
> (ApplicationId) the logs are not generated for the Dags that completed, as a
> result the user needs to wait till all queries complete.
> This behavior makes it very difficult to isolate failures per query as a
> single log file will have results from multiple queries.
