Does this part of the manual for bash help?


       When bash is started non-interactively, to  run  a  shell  script,
for
       example, it looks for the variable BASH_ENV in the environment,
expands
       its value if it appears there, and uses the expanded value as the
name
       of  a  file to read and execute.  Bash behaves as if the following
com-
       mand were executed:
              if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
       but the value of the PATH variable is not used to search for  the
file
       name.


In particular setting BASH_ENV on the local side and then using -o
SendEnv=true might do something useful (or not!).

There is also a hadoop-env.sh file in the hadoop configuration that might be
useful.  You could do something like . ~/bash_profile there.

None of these are good answers.  I have exactly the same problem with lots
of my EC2 invoking scripts.  There, I build a script, throw it over to the
new instance and the first few lines source key profile files.  Not a good
solution, but at least it works.  For Mahout running hadoop, this is a whole
lot less viable.
