facing problems while configuring hipi

[Neeraj Kasliwal]

  I have configured hadoop 0.20.1 on my machine. I have also run sample map - reduce program on hadoop using eclipse. but while executing Downloader program i was getting following errors even i have added hipi-dev/release/hipi-0.0.1.jar to project build path.

i have given input path for this program as /user/hduser/links/input.txt and output path as /user/hduser/links/output.hib

Errors:-

Output HIB: /user/hduser/links/
