      Description

      "randomWrite" mode of PerformanceEvaluation (PE), with nclients > 1, does random writes only within a small range rather than across all rows.

      e.g, for:

      ./bin/hbase org.apache.hadoop.hbase.PerformanceEvaluation --nomapred --rows=1000 randomWrite 10

      [Note: As per convention in all modes of PE, --rows is the number of rows per client]

      So for the above, with # of clients set to 10, currently all clients generate writes to keys in the 0..999 range instead of the 0..9999 range.

      [Fix appears to be simple. Will provide a patch.]
