Bryan Duxbury commented on HBASE-481:
-------------------------------------

That's a notable improvement. We can live with that for the time being.

To be clear, my previous suggestion was not to use addContent at all. Instead, 
use the TestRegionRebalancing approach, and just forge N regions with hardly 
any rows in them.

> Use smaller dataset in TestTableIndex and TestTableMapReduce

> TestTableIndex and TestTableMapReduce rely on MakeMultiRegionTable, which in 
> turn calls addContent in HBaseTestCase. This method produces 17k rows in the 
> table, and something like 10 regions. That's a lot more than we actually need 
> to prove the functionality of TTI and TTMR. 
> Can we reduce the number of rows that we use by shortening the run of 
> addContent? Is there any risk in changing addContent globally to produce less 
> data?
