INLINE COMMENTS
  src/main/java/org/apache/hadoop/hbase/loadtest/GetGenerator.java:81 Should be seeded.
  src/main/java/org/apache/hadoop/hbase/loadtest/RandomDataGenerator.java:94 Please seed as
what is done at line 61.
  src/main/java/org/apache/hadoop/hbase/loadtest/KeyCounter.java:103 I think we should add
some message to NoKeysException so that this scenario can be distinguished from that of line
90.
