Hari Mankude commented on HDFS-4873:
------------------------------------
The sequence of operations for creating the problem
1. create a file of size one block
2. take a snapshot
3. append some data to this file.
4. use DfsClient.callGetBlockLocations() to get block locations of the snapshot
version of the file. The file len is specified as Long.MAX_VALUE.
5. This call returns two LocatedBlocks for the snapshot version of the file
instead of one block.
> callGetBlockLocations returns incorrect number of blocks for snapshotted files
