Keith Turner commented on ACCUMULO-1409:
----------------------------------------
bq. the only way I can guarantee the integration tests don't time out is if I
enable the native maps with "-P native".
Interesting, I wonder if this is because JavaGC is avoided and/or the native
maps are faster at sorting.
So native map support has recently been added to MAC. I have taken a quick
look at the code, but not recently. It seems like native maps can be used when
Accumulo itself uses MAC. However what about the case where an end user uses
MAC? Can this be supported? It seems like supporting this would require
putting jars maven repos that contain the shared libs.
> Make MiniAccumuloCluster support native maps

> 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.
