> -------------------------------------------
>                 Key: HDFS-4875
>                 URL: https://issues.apache.org/jira/browse/HDFS-4875
>             Project: Hadoop HDFS
>          Issue Type: Sub-task
>          Components: snapshots, test
>            Reporter: Tsz Wo (Nicholas), SZE
>            Assignee: Arpit Agarwal
>            Priority: Minor
> 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.
