Raghu Angadi commented on HADOOP-1932:
--------------------------------------
Isn't it true that no blocks are guaranteed to be present unless the file is
closed? Adding one more byte, only makes the issue less probable, right?
Flusing to datanodes is guaranteed (by implementation, not by contract) even
while writing exactly two blocks. What is not guaranteed is datanodes reporting
the block to Namenode.
