             Summary: Introduce a wrapper over ByteBuffer to ensure 
immutability of data while flushing the data
                 Key: HDDS-1375
                 URL: https://issues.apache.org/jira/browse/HDDS-1375
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Client
    Affects Versions: 0.5.0
            Reporter: Mukul Kumar Singh


After HDDS-372, ByteBuffers can be converted to Bytestring using 
UnsafeByteOperations. Please refer the link and HDDS-372 for details 
https://developers.google.com/protocol-buffers/docs/reference/java/com/google/protobuf/UnsafeByteOperations.

This jira proposes to create a wrapper over ByteBuffer to ensure the buffer is 
marked immutable while it is being flushed.
