Not necessarily. We may have one profile only if we don't have many
variations. Few I can see [Xms, Xmx, NewSize, MaxNewSize]
IMHO, user can take advantage of community recommendations (GC collection
algorithm - HBase documentation, DirectMemorySize - HDFS-3600).

Also, if possible we can extend this profiles concept to HBase
configurations as well.
