---------------------------------------
OK... So only an issue in 0.94. Cool.
> The Region is not being split and far exceeds the desired maximum size.

> We are seeing this behavior when creating indexes in one of our environment.
> When an index is being created, most of the "requests" go into a single
> region. The amount of time to create an index seems to take longer than
> usual and it can take days for the regions to compact and split after the
> index is created.
> Here is a du of the HBase index table:
> {code}
> -bash-4.1$ sudo -su hdfs hadoop fs -du /hbase/43681
> 705 /hbase/43681/.tableinfo.0000000001
