I have a question about the availability of the Tez web UI in Pig on Tez. The Pig ‘Performance and Efficiency’ doc states, "Tez specific GUI is not available yet, there is no GUI to track task progress. However, log message is available in GUI.” What does this mean, precisely? We have not deployed and configured the Tez UI described here: https://tez.apache.org/tez-ui.html. Will that UI work when running Tez on Pig? If so, what does ‘Tez specific GUI is not available yet’ mean?
What I am most specifically concerned about is the ability to see which Pig aliases are being assigned to which Tez vertices, or failing that, which Pig aliases are being processed by a particular Tez DAG. This is currently not available in logs in pig 0.15.0, although I’m aware it is in master. What are best practices for Pig 0.15.0? Thanks, Kurt
