Tsz Wo (Nicholas), SZE commented on HADOOP-3992:
------------------------------------------------
- need "return -1" when writePr<0 || writePr>1 and readPr<0 || readPr>1
- the symbol MS for millisecond may be confusing because Ms means megasecond.
- new File("/tmp") may not work in the OS not using "/" as the separator
charcter.
- In LoadGenerator.DFSClientThread.nextOp(), "float" should be "double"
> Synthetic Load Generator for NameNode testing
