Subject [jira] [Commented] (ACCUMULO-1409) Make MiniAccumuloCluster support native maps
Date Sat, 24 Aug 2013 01:59:51 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13749239#comment-13749239

Corey J. Nolet commented on ACCUMULO-1409:
------------------------------------------

Being able to add an environment variable like ACCUMULO_NATIVE_LIB pointing to the native
maps would be something I'd be interested in having. This would work for both full Accumulo
installs AND for the MAC. This would also allow people using the MAC as a single-node Accumulo
to use this configuration param as well.

> 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.
