Tsz Wo (Nicholas), SZE commented on HADOOP-4862:
------------------------------------------------

+1 patch looks good, some nits:

- "Convets" should be "Converts"
- ioeToSocketException should be static
- "Cange" should be "Change"

> A spuriou IOException log on DataNode is not completely removed

> HADOOP-3678 fixes a spurious warning log in DataNode, in most cases. This log 
> is still possible in some cases.
> For e.g. The exception is still logged if the client closes the connection 
> after DataNode writes all the block data but before it writes final 4 bytes 
> to indicate end of data.
