It appears that ElasticSearch wants to mimic Lucene's defaults in FSDirectory#open (https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/index/store/IndexStoreModule.java#L51)

Lucene's defaults now include Linux in addition to Solaris and Windows when considering MMapDirectory (https://issues.apache.org/jira/browse/LUCENE-3198)

ElasticSearch should follow suit and, according to a lot of discussions on the mailing list, many are already doing this via configuration.

Hi @aochsner, I've merged this only to master, since it's a pretty major change and we don't want to change the defaults for the 0.90.x releases. It will be part of the next 1.0 beta release.

Thanks!
