Hi,
My nutch 0.8 intallation is 1 week old and has
been pretty stable. Today I was doing some
house-keeping, removing directories etc. Then I run
the stop-all/start-all and I see this exception in the
hadoop-nutch-jobtracker-data.log. It is constantly
spewing out this exception, and I have a broken system
:(
I have tried applying the Lease patch
(DFSClient.java (revision 423872)
) and have also upgraded to 0.4.1 with no solution.
