Aaron T. Myers commented on HDFS-3960:
--------------------------------------
Hi Konstantin, I agree that a solution like you describe should be sufficient.
It sounds very similar to what is described in the "Super Sync" option of the
design document I posted on HDFS-2802. Would you mind taking a look at that
section of the document to see if it is inline with what you're describing here?

> Here is a design question: Suppose there is a being written file when a
> snapshot is being taken. What should the length of the file be shown in the
> snapshot? In other words, how to determine the length of being written file
> when a snapshot is being taken?
