Wait till there not regions in RIT instead of sleep like how we have done in
TestMasterFailover
{code}
log("Waiting for no more RIT");
ZKAssign.blockUntilNoRIT(zkw);
{code}

>
> PerformanceEvaluation a quick way to 'benchmark' a HBase cluster. The
> current 'write*' operations do not pre-split the table. Pre splitting the
> table will really boost the insert performance.
> It would be nice to have an option to enable pre-splitting table before the
> inserts begin.
> it would look something like:
> (a) hbase ...PerformanceEvaluation --presplit=10 <other options>
> (b) hbase ...PerformanceEvaluation --presplit <other options>
> (b) will try to presplit the table on some default value (say number of
> region servers)
