[jira] [Created] (NIFI-302) nifi-write-ahead-log has potential for corruption if out of disk space on checkpoint

Mark Payne created NIFI-302:
-------------------------------

             Summary: nifi-write-ahead-log has potential for corruption if out of disk space on checkpoint
                 Key: NIFI-302
                 URL: https://issues.apache.org/jira/browse/NIFI-302
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework, Tools and Build
    Affects Versions: 0.0.1
            Reporter: Mark Payne


If a partition in the write-ahead-log throws an IOException while in the rollover() method (called from the checkpoint method of MInimalLockingWriteAheadLog), the partition is not blacklisted. As a result, it can still be written to, and this can cause corruption if it is then written to again before being rolled over.
