Description

Add support for humongous tables via a hierarchical layout for regions on filesystem.

Credit for most of this code goes to Huaiyu Zhu.

Latest version of the patch is available on the review board: https://reviews.apache.org/r/36029/

Known limitation of this patch: It does not deal with HFileLinks, which means that humongous tables, as implemented in this patch, would not support snapshots or timeline consistent region replicas feature in their current form. This could be addressed later but we had decided not to implement HFileLink support for the first version.
