Subject Hive shell not using manually set tez container size
Date Fri, 02 Dec 2016 06:32:28 GMT
Not really sure if this is an issue on the Hive or Tez side, but when we
open a Hive shell and set tez.task.resource.memory.mb to a different value
than listed in tez-site.xml, the query that's run doesn't seem to pick up
the setting and instead uses the one in the config file. However, if we let
the Tez session timeout within the shell, then set the tez task memory to
some value, the query run in the new session will use the manual setting as
expected. Also, if you set the option as a command line setting when
launching the hive shell, it will also use the manual setting as expected.

Has anyone else run into this as well or know what the root cause of this
behavior is?
Using Hive 2.0.1 and Tez 0.8.4.
