> Because bin/hadoop and bin/hdfs put the entire CLASSPATH in the command line arguments,
it exceeds 4096 bytes, which is the maximum size that ps (or /proc) can work with. This makes
looking for the processes difficult, since the output gets truncated for all components at
the same point (e.g. NameNode, SecondaryNameNode, DataNode).
> The mapred sub-project does not have this problem, because it calls "export CLASSPATH"
before the final exec. bin/hadoop and bin/hdfs should do the same thing
