Jing Zhao commented on HDFS-4875:
---------------------------------
Thanks for adding the test, Arpit! The patch looks good to me. Only one minor
nit: the RANDOM field can be removed because it has not been used.
> Add a test for testing snapshot file length

> Here is a test idea from Suresh:
> - A file was length x at the time of snapshot (say s1) creation
> - Later y bytes get added to the file through append
> When client gets block locations for the file from snapshot s1, the length it
> know is x. We should make sure it cannot read beyond length x.
