> A discussion on the HBase user mailing list (http://markmail.org/thread/7leeha56ny5mwecg)
led to some suggested improvements for the org.apache.hadoop.hbase.client.HTablePool class.
> I will be submitting a patch that contains the following changes to HTablePool:
> * Remove constructors that were not used.
> * Change access to remaining contstructor from public to private to enforce use of the
static factory method getPool.
> * Change internal map from TreeMap to HashMap because I couldn't see any reason it needed
to be sorted.
> * Remove HBaseConfiguration and tableName member variables since they aren't really properties
of the pool itself. They are associated with the HTable that should get instantiated when
one is requested from the pool, but not already there.
