Hi, We are currently experiencing some issues where the lock on our index isn't being released properly (for some reason). Our indexing process ends with close() being called on all the writers that were used in the indexing process.
We currently use the default NativeFSLockFactory <https://lucene.apache.org/core/4_3_0/core/org/apache/lucene/store/NativeFSLockFactory.html> but are considering trying one of the other ones. I am looking at SimpleFSlockFactory <https://lucene.apache.org/core/4_3_0/core/org/apache/lucene/store/SimpleFSLockFactory.html> where the only code change would be to unlock the index directory before indexing to account for any abnormal JVM exits. Is this something that would function well in both a local storage/NFS based environment? This is my only worry since some of our servers use NFS while others use local storage. For good measure, the exception I am getting is: LockObtainFailedException: Lock obtain timed out: NativeFSLock@ /home/DEV01/index/1/write.lock This is on a non-NFS system. Kind regards, Frederik
