localdisk of submit node. it runs chmod 0777 on -files and if after
that files is not readable/writable/exists it throws error.

Currently, if anythin is wrong with streaming job, it dies without
any explanation.
Before creating and running actual MapReduce job, Streaming should
check if:
-- the executables (or scripts) for -mapper and -reducer are
available and have right permissions
-- the input fragments exist
