I am trying to verify something here.. I run mapred with
local option. These
are trivial issues but need to be addressed at some point of
time
Right now two /tmp directories are created ( one in the
running directory)
Let us say /nutch/tmp
and another in the root folder /tmp
Following are the questions
1)Are there supposed to be two instances of /tmp folder ?ie
/tmp and as well
as /nutch/tmp
2) Where are these directories supposed to be
system
/tmp/hadoop/mapred/system ????
or
/nutch/tmp/hadoop/mapred/system ????
2) Map files
local directory in
/tmp/hadoop/mapred/local ????
or
/nutch/tmp/hadoop/mapred/local ????
3) Are we trying to store some user related files when we
have /nutch/tmp.
Why cant we keep it as
/tmp/hadoop/ in all the systems (including task tracker and
job tracker)
