startFileInternal should return the last block of the file opened for append as an under-construction block
-----------------------------------------------------------------------------------------------------------

Key: HDFS-1363
URL: https://issues.apache.org/jira/browse/HDFS-1363
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 0.21.0
Reporter: Konstantin Shvachko
Fix For: 0.21.1


{{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.
