    Description

      FSNamesystem.startFileInternal should convert the last block of the file opened for append to an under-construction block and return it. This will let remove the second synchronized section in FSNamesystem.appendFile() and avoid redundant computations and potential inconsistencies as stated in HDFS-1152.
