Is there documentation that explains how Nutch does locking? According to the Lucene doc, the lock should go in java.io.tmpdir, but I never see anything looking like a lock file appear there. I do see a file "write.lock" in the directory where the Lucene index lives.
But strangely, that file is never removed, and sometimes I then get lock acquire timeouts. the Luke application, in particular, always complains that the index is locked. I am only crawling to the local filesystem, not a HDFS. Is there something special Nutch does to lock the Lucene index?
