----------------------------------------------------------------
Doc note: This creates four configuration parameters, so they will need to be
documented in the wiki after hbase-metastore-branch gets merged to trunk. In
the meantime, I'm linking this issue to HIVE-9752 (Documentation for HBase
metastore).
The new parameters are:
* hive.metastore.hbase.aggr.stats.cache.entries
* hive.metastore.hbase.aggr.stats.memory.ttl
* hive.metastore.hbase.aggr.stats.invalidator.frequency
* hive.metastore.hbase.aggr.stats.hbase.ttl

> HBase can easily manage the scale of caching aggregated stats we should be
> using it to do so.
