You can try to run it via LocalJobRunner ("hadoop jar yourjar -jt
local" if you're using GenericOptionsParser), and see if it exhibits
the same behavior there. It's easy to push that into a debugger
(HADOOP_OPTS="-Xdebug
-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8020" and
point Eclipse at it) to set some breakpoints and see what's going on.

How do I figure out whats going on while a job is trying to initialize? I
have a job thats importing data from a DB into HBase and it takes very long
to initialize. The time is enough to cause a time out of the mappers and
eventually kill the job.
