MapR is stepping up the feature set of its Hadoop software, announcing on Tuesday the addition of support for the YARN resource manager and the ability to run HP’s Vertica analytics software directly atop the MapR file system. The latter feature, in particular, is emblematic of MapR’s approach to keeping up with — or even passing in some areas — Hadoop mindshare (and presumably marketshare) leaders Cloudera and Hortonworks.

YARN is the resource management technology that became part of Apache Hadoop with its 2.0 release in 2012 (and which was just granted general availability status in 2013). YARN lets multiple computing frameworks run on the same Hadoop cluster using the same underlying storage.
