> [TestClient-1] hbase.PerformanceEvaluation: Start class
> org.apache.hadoop.hbase.PerformanceEvaluation$SequentialWriteTest at offset
> -1138166308 for -21474836 rows
>
> this is due to variable totalRows in TestOptions defined by int(-2147483648
> --- 2147483647), One GB is 1048576(1024*1024) by default. The max value of
