-----------------------------------
Priority: Minor (was: Major)
Assignee: Andrew Purtell
I'll take this on as one of the things to do before the 0.98.0 RC. If someone
else would like to put up a patch, feel free to reassign though.
> use HDFS advisory caching to avoid caching HFiles that are not going to be
> read again (because they are being compacted)

> HBase can benefit from doing dropbehind during compaction since compacted
> files are not read again. HDFS advisory caching, introduced in HDFS-4817,
> can help here. The right API here is {{DataInputStream#setDropBehind}}.
