Hello,
Any opinions about a problem we have with 0.9 are appreciated.
The problem is that hits are found via command line NutchBean
invocation, (in this small test case 333 hits) however, the result set
is zero hits due to the exception. Luke also accesses these same indexes
just fine.
Got the Hadoop patch that was referred to in the archives, because the
description seemed applicable, however it appears to be the same version
of hadoop-core: 12.2.2 that came with nutch 0.9. Is that patch already
integrated into the most recent 0.9 nutch release or is it otherwise not
applicable? Can someone tell me what the problem is given the exception
in the log below?
Thanks.
