Hello Jacquelyn,
This is very odd:
> Unexpected EOF in prolog
> at [row,col {unknown-source}]: [1,0]
We've fixed this problem a long time ago. It was a problem of non-unicode
codepoints in the data sent to Solr. The Solr indexing plugin strips them all,
and to my knowledge, there are no other non-unicode codepoints to strip.
What you can do to analyze the problem is to use debug or even trace logging,
so you can see the exact XML Nutch is sending on the wire, and use a hexeditor
to check for position 1,0, well, the first few bytes.
