Christopher Tubbs commented on ACCUMULO-1409:
---------------------------------------------

I think I'd prefer to use a standard environment variable, like [LD_LIBRARY_PATH|http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html#AEN80].
See also [Fedora's Java Packaging Guidelines|https://fedoraproject.org/wiki/Packaging:Java#Guideline]
for other standards/guidelines/ideas on how to locate native libraries.

> If a user sets up a single node accumulo instance and uses it for testing, then w/o native
maps the performance will not be as good as it could.  I did some testing of the new GC in
java 7, along the way I noticed a significant difference between the native map and java map.
