Dear Mr/Miss:
Sorry to interrupt you but there are two problems to ask you for help. It
puzzles us for a long time.
We built a local wiki using mediawiki by downloading the page articles
fromhttp://download.wikimedia.org/enwiki. However, the data cannot be imported completely
by virtue of the mwdumper.jar and it stopped halfway saying that there is
IllegalArguments. We tried different source data but no use. Is there something wrong
with our configuration?
mwdumper.jar may not be able to recognise the most recent format. I
remember that there were some patches available somewhere.
