Phu Hoang commented on HADOOP-2574:
-----------------------------------
Arun,
the tutorial addresses all the bugs that I encountered. Great job!!
I was not able to detect that you resolved the smaller confusion (not
show stopper) of whether these examples work if you were in stand-
alone mode or not.
I was able to run WordCount v1.0 using local input and output
directories (not HDFS). I was NOT able to run WordCount v2.0 using
local input and output directories, only HDFS input and output
directories work there. It would be good to set the reader's
expectation.
I could see people trying the examples out without doing HDFS first,
and may run into issues with WordCount v2.0.

> The javac and jar command are also wrong, they don't include the directories
