             Summary: Seek to file end throws EOF Exception
                 Key: HDDS-2692
                 URL: https://issues.apache.org/jira/browse/HDDS-2692
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
            Reporter: Ayush Saxena
            Assignee: Ayush Saxena


Seek to File Length position throws EOF.
Seeks by default should throw EOF past FileLength, not at file length position.

Even in DFSInputStream it throws EOF above FileLength :

{code:java}
  public synchronized void seek(long targetPos) throws IOException {
    if (targetPos > getFileLength()) {
      throw new EOFException("Cannot seek after EOF");
    }
{code}

Due to this behaviour EOF is shown as part of tail command too.
