Hi,

I’m = trying to understand the directory structure of Hadoop.

My = understanding is HADOOP_TMP_DIR is the base directory for everything = that is not specified.

Why is that? = (TMP seems to indicate temporary directory, i.e. = ephemereal).

Where can I lookup directory & variables that can = be specified?

I’d like to get some logical separation by = function (performance, scalability, availability, = etc.).

Many Thanks, Caesar.
