  [https://issues.apache.org/jira/browse/HADOOP-1476 HADOOP-1476] adds to HBase {{{src/test}}}
the script {{{org.apache.hadoop.hbase.PerformanceEvaluation}}}.  It runs the tests described
in ''Performance Evaluation'', Section 7 of the [http://labs.google.com/papers/bigtable.html
BigTable paper].  See the citation for test descriptions.  They will not be described below.
The script is useful evaluating HBase performance and how well it scales as we add region
servers.

  This first test ran on a mini test cluster of four machines only: not the 1768 of the !BigTable
paper.  Each node had 8G of RAM and 2x dual-core 2Ghz Opterons.  Every member ran a HDFS datanode.
 One node ran the namenode and the HBase master, another the region server and a third an
instance of the !PerformanceEvaluation script configured to run one client.  Clients write
~1GB of data: One million rows, each row has a single column whose value is 1000 randomly-generated
bytes (See the BigTable paper for a better description).
