<description>The interval at which we record offsets in hbase
store files/mapfiles. Default for stock mapfiles is 128. Index
files are read into memory. If there are many of them, could prove
a burden. If so play with the hadoop io.map.index.skip property and
skip every nth index member when reading back the index into memory.
+ Downside to high index interval is lowered access times.
