Subject Re: Helpers for MAPREDUCE-3727 scenario
Date Tue, 10 Mar 2015 19:32:51 GMT
Tez does provide some config helpers - to translate configs between MR and
Tez. I'm not sure which downstream projects actually make use of these. We
could add some cleanup code here / or a new helper - but it'll be up to the
users to actually make use of this in the correct place.
For the specific property (mapreduce.job.credentials.binary) - Tez uses
it's own property for this - which I believe Pig / Hive setup. If I
understand the usage correctly - Oozie should only be loading this property
in the launcher, which should have a separate configuration from the actual
job. Does Oozie leak these configs into the configs for the main job ?
