I'd like to minimize clutter and unneeded values in the core-, hdfs-, and
mapred-site.xml files that appear on the master, and that appear on the
slaves, only having those that are actually used in the files on the
NN/SNN/JT, and in the files on the DNs/TTs. Some values are clearly only
needed on the master or only on the slaves, or on both, but for many it's
not clear.
Is there a summary containing this information? I know that in the
distribution's docs directory the {core|hdfs|mapred}-default.html files list
all values, with defaults and descriptions, but not always on what daemon(s)
they're needed.
Thanks.
