Lucence uses files for locking. The default locking file is stored in Java. io. tmpdir, you can use-dorg. apache. lucene. lockdir = xxx specifies the new dir with write. lock commit. lock two files. The lock file is used to prevent parallel operations on indexes. If parallel operations are performed, Lucene throws an exception. You can disable locking by setting-ddisablelucenelocks = true. This is generally dangerous, unless you have read-only guarantee for the operating system or physical leve
