Roman Shaposhnik updated HIVE-2757:
-----------------------------------
Attachment: HIVE-2757.patch.txt
Here's an example patch that is not meant for inclusion, but rather to generate
discussion whether such an approach would be acceptable.
Basically, the fundamental problem is that Hive java code can be used in other
projects (like Oozie) and hence it can't rely on launcher shell scripts always
passing correct set of properties along based on querying the environment at
shell level.
This unique feature of Hive makes discovery of Hadoop executor script happen at
the level of Java code. The patch contains a very naive attempt at doing that
while maintaining backward compatibility with Hadoop 0.20.X and older releases.
The most notable feature that is still missing is an ability to discover
Hadoop that's part of the user's PATH. Before I implement that, however, I'd
like to ask whether exec'ing via ProcessBuilder won't be a better option,
rather than me manually tying to parse PATH (error prone).
Please let me know what you think.
P.S. I have also took the liberty of removing ConfVars.HADOOPCONF since I don't
think it is used anymore.
