Github user markap14 commented on the issue: https://github.com/apache/nifi/pull/2502 @alopresto This is not really for a corrupted flowfile repository but rather for a flowfile repo that points to content that no longer exists. So the easiest thing would be to create a GenerateFlowFile that generates at least 1 byte of data, then stop NiFi with data queued up and blow away the content repo..... or change your nifi.properties to look at a different location for the content repo.
