Nick Dimiduk commented on HBASE-9808:
-------------------------------------
{noformat}
+ TableMapReduceUtil.addDependencyJars(job);
+ // Add a Class from the hbase.jar so it gets registered too.
+ TableMapReduceUtil.addDependencyJars(job.getConfiguration(),
+ org.apache.hadoop.hbase.util.Bytes.class);
+ TableMapReduceUtil.initCredentials(job);
{noformat}
the call to {{addDependencyJars(Configuration, Class)}} is not necessary
because you've already called {{addDependencyJars(Job)}}.
{noformat}
void testRow(final int i) throws IOException {
if (this.testScanner == null) {
Scan scan = new Scan(format(this.startRow));
+ scan.setCaching(30);
scan.addColumn(FAMILY_NAME, QUALIFIER_NAME);
this.testScanner = table.getScanner(scan);
}

Our value in hbase-default.xml is now 100. What's the reason for lowering this
value?
{noformat}
+ * This method takes some time and is done inline uploading data. For
+ * example, doing the mapfile test, generation of the key and value
+ * consumes about 30% of CPU time.
+ * @return Generated random value to insert into a table cell.
{noformat}
Yikes! This is throwing off the performance number then?
There's still trailing whitespace in places.
