Subject Help:how to read a xml file in hadoop framework
Date Thu, 10 Jun 2010 08:20:41 GMT
Dear all,

I need to read a xml file in my application. When i run it as an application in eclipse, it
runs correct, but when I run it on Hadoop, it gives the error message:

10/06/10 15:52:52 INFO input.FileInputFormat: Total input paths to process : 22

From the error message, We can see the xml file can't be found.
Hope you can help me, thanks.

Best regards
