Daryn Sharp commented on HADOOP-5983:
-------------------------------------
Unfortunately, no, I'm swamped with other 205 work. Feel free to take it!
Perhaps you already debugged the issue and know this:
# the mapred-site.xml should not be read in the first place
# the reporter's mapred-site.xml includes local-mapred-site.xml, but the latter
file does not exist
# I think the "solutions" are one of:
#- code change: Namenode doesn't include mapred-site.xml, but I very vaguely
remember there was problem that made it a non-trivial change
#- user change: Don't have mapred-site.xml include a non-existent
local-mapred-site.xml
#- user change: Create local-mapred-site.xml as a blank file
205 has a lot of change as it is, so I'd be hesitant to add another potentially
incompatible change when the issue is arguably "user error". Someone,
somewhere, might incorrectly be relying on settings being read from
mapred-site.xml that shouldn't be in that file. I wouldn't make that case for
anything but the 20.x line, but I'm by no means going to block the real fix if
it's deemed necessary.
