Subject Re: Is hadoop-streaming.jar part of the Apache distribution?
Date Sat, 01 Jan 2011 00:02:57 GMT
I went to the top Google hit for "Hadoop streaming" and didn't notice that
this was the 0.15.2 documentation instead of the one that matches my
version.

However, the 0.20.2 documentation has the same error:
http://hadoop.apache.org/common/docs/r0.20.2/streaming.html#Hadoop+Streaming
.

I verified that this is also the case with the files installed locally in my
/opt/local/hadoop-0.20.2/docs folder.

Is there a place I should file a documentation bug?
