Kai Zheng updated HDFS-8430:
----------------------------
Attachment: HDFS-8430-poc1.patch
Uploaded a poc patch with a test:
This test serves a prototype to demo the idea proposed so far. It creates two
files using the same data, one is in replica mode, the other is in stripped
layout. For simple, it assumes 6 data blocks in both files and the block size
are the same. We can change the test codes to try other ideas if any.
Comments are welcome!
