nutch0.8.1+dfs fetch return nothing

[xu xiong <xi...@gmail.com>]

Hi there,

I set up nutch 0.8.1 on a linux box, and it works.
Then I follow http://wiki.apache.org/nutch/NutchHadoopTutorial to set
up nutch using dfs.
I finished all the inject,generate,fetch,invertlink,index steps, but I
just cannot search anything.
It took me hours to find out that in the fetch step, it just fetch nothing.
And, in the hadoop logs the following keep occur:
2007-03-05 17:41:25,334 WARN  fs.FSNamesystem - Zero targets found,
forbidden1.size=2 forbidden2.size()=0
2007-03-05 17:41:25,334 WARN  fs.FSNamesystem - Zero targets found,
forbidden1.size=2 forbidden2.size()=0
2007-03-05 17:41:25,422 WARN  fs.FSNamesystem - Zero targets found,
forbidden1.size=2 forbidden2.size()=0
...[lots of warning]

Anyone know what's problem?

Thanks in advance,
