Hadoop Append (0.19) works in same way as GFS does? GFS algorithm is below:
Application originates record append request. 2. GFS client translates request and sends it to master. 3. Master responds with chunk handle and (primary + secondary) replica locations. 4. Client pushes write data to all locations. Primary checks if record fits in specified chunk. 6. If record does not fit, then the primary: . pads the chunk, . tells secondaries to do the same, . and informs the client. . Client then retries the append with the nextchunk. 7. If record fits, then the primary: . appends the record, . tells secondaries to do the same, . receives responses from secondaries, . and sends final response to the client.
