--------------------------------------------
Summary: Add a test for testing snapshot file length
Key: HDFS-4875
URL: https://issues.apache.org/jira/browse/HDFS-4875
Project: Hadoop HDFS
Issue Type: Test
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.
