The .dot file is generated into the Tez Application Master’s container log dir. Firstly, you need to figure out the yarn application in which the query/Tez DAG ran. Once you have the applicationId, you can use one of these 2 approaches:
1) Go to the YARN ResourceManager UI, find the application and click through to the Application Master logs. The .dot file for the dag should be visible there. 2) Using the application Id ( if the application has completed), get the yarn logs using “bin/yarn logs -applicationId <appId>” - once you have the logs, you will be able to find the contents of the .dot file within them. This approach only works if you have YARN log aggregation enabled. thanks — Hitesh On Sep 30, 2015, at 5:29 PM, James Pirz <james.p...@gmail.com> wrote: > I am using Tez 0.7.0 on Hadopp 2.6 to run Hive queries. > I am interested in checking DAGs for my queries visually, and I realized that > I can do that by graphviz once I can get "dot" files of my DAGs.
