Description

In the Nutch parse step, I received the following error. It seems the parse-tika plugin has broken.

$ /cygdrive/d/nutch_trunk/runtime/local/bin/nutch parse -D mapred.reduce.tasks=2 -D mapred.child.java.opts=-Xmx1000m -D mapred.reduce.tasks.speculative.execution=false -D mapred.map.tasks.speculative.execution=false -D mapred.compress.map.output=true -D mapred.skip.attempts.to.start.skipping=2 -D mapred.skip.map.max.skip.records=1 crawlId/segments/20141118235323
