liang xie commented on HDFS-4301:
---------------------------------

[~tlipcon], IMHO the current implement seems OK,  we can enlarge 
DFS_IMAGE_TRANSFER_RATE_KEY && DFS_IMAGE_TRANSFER_TIMEOUT_KEY to relieve, right 
?
or if you have better idea, could you shed some light on it,  thanks in advance.

> HDFS-1490 added a timeout on image transfer. But, it seems like the timeout 
> is actually applying to the entirety of the image transfer operation. So, if 
> the image or edits are large (multiple GB) or the transfer is heavily 
> throttled, it is likely to time out repeatedly.
