How to trace the requests executed on the cluster ?

Hello, is it possible to trace the requests executed on the cluster? This would allow me to identify possible requests at risk (SELECT * ..)

Thanks

Hi @Clément Dumont!

In hive you can try to investigate the query by looking for a parameter called hive.query.string.
E.g.

BTW it works for Hive on Tez or Hive on MR (in this case you'd see on Yarn Web UI).
Hope this helps!
