Tsz Wo (Nicholas), SZE commented on HDFS-5222:
----------------------------------------------

Thanks Arpit and Junping for reviewing the patch.

> ... couple of spurious newlines. ...

I intentionally added the new lines to separate the different groups of fields.

> Shall we rename it to something like: notEnoughSpace? ...

You are right that notEnoughSpace is much better.  However, I will remove the 
method due to the comment below.

> Shall we remove checking node's remaining ...

Sure, let's remove it.

Here is a new patch: h5222_20130824.patch 
                
> Move block schedule information from DatanodeDescriptor to DatanodeStorageInfo

> In HDFS-4990, the block placement target type was changed from 
> DatanodeDescriptor to DatanodeStorageInfo.  The block schedule information, 
> such as the number of blocks scheduled for replication (i.e. 
> getBlocksScheduled()), should be moved from DatanodeDescriptor to 
> DatanodeStorageInfo.
