Subject Why is HADOOP_TMP_DIR the base directory?
Date Sun, 21 Jun 2015 17:33:25 GMT
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.
