Hello All,
I am trying to make changes to YARN as part of my research project.
Regarding this, I have a few queries from this group:-
1) I wanted to have a feature in YARN such that users can run reducers at
specific nodes. Is such a feature already present in YARN?
YARN supports running any task on a specific node. The issue is that
the MapReduce application master does not currently offer a way to ask
for it.
2) In order to contribute to the hadoop code base, I forked out a local
github repository from the apache repository. This gave me version 3.2.0,
which I think is the current development version.
If I want to do my changes on the current stable version, i.e. 3.0.3, how
do I do that? I realize this should be a simple git command, but I wanted
to double check before I start digging in to the code.
All changes should be done against the trunk. Assuming your changes are
committed, the committer will cherry pick them into the relevant releases.
