Subject [jira] [Commented] (ACCUMULO-1409) Make MiniAccumuloCluster support native maps
Date Sun, 21 Jul 2013 12:46:48 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13714697#comment-13714697

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

Native libraries can be maven artifacts themselves. They don't have to be carried in a jar.
In fact, I plan on experimenting putting native maps in their own module in ACCUMULO-210.
The new accumulo-maven-plugin could grab the native map library for their platform from their
local maven repo. If users aren't using accumulo-maven-plugin, the accumulo-minicluster could
have an optional dependency on a accumulo-native module, and if users want to use it, they
can declare it as an explicit dependency, so it gets put on the classpath for their execution
of MAC.

> 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.
