Subject [jira] [Commented] (ACCUMULO-1409) Make MiniAccumuloCluster support native maps
Date Fri, 17 May 2013 01:54:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13660257#comment-13660257

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

If {noformat}bin/accumulo mini{noformat} is used to start a Single Node Accumulo, the native
maps should work out of the box (though the user will have to override the tserver.memory.maps.native.enabled
property in the MAC's site config). Are we interested in seeing if native maps may help us
in our pursuit to speed up the MAC during the automated integration tests?

> 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.
