Thomas Graves commented on SPARK-5493:
--------------------------------------
Basically oozie is the one that does the proxyuser doas. Do you know why hive
doesn't just have this code? I assume it already has code for similar to this
for running on MR because MR doesn't have any special options for the PROXY
user.
Somewhat of a side note, hadoop has an env variable HADOOP_PROXY_USER that
basically does this for you if set. I the code is better for production type
usages but if it were just testing or user level that would work.
I guess its not that big of a deal as this needs to be done somewhere but I
think the description is a bit misleading and its inconsistent with how it is
done across components now.
