Doug Cutting commented on HADOOP-1047:
--------------------------------------

Do we really need a new option in hadoop-default.xml?  If this is only used by 
test code, then it probably does not need to be documented in 
hadoop-default.xml, as that will just confuse folks.  So we might remove that, 
no?

> TestReplication fails because DFS does not guarantee all the replicas are 
> placed when a file is closed

> TestReplication asserts that the number of replicas that a file has is equal 
> to its replication factor immediately after a file is closed. But DFS only 
> guarantees  the minimun number of replicas is placed when a file is closed. 
> This leads to occasional failure of TestReplication.
