I tried running infinispan in two machines and persisted the index data in one machine. When i try to run simultaneously in 2 machines with indexing and persisting(cache-store) into the database, i am getting the following exception,
Caused by: java.io.FileNotFoundException: Error loading metadata for index file: segments_2j|M|Course
