Zhe Zhang updated HDFS-7782:
----------------------------
Attachment: HDFS-7782-005.patch
005 patch implements pread (non-hedged). It also moves 2 utility functions from
{{TestRecoverStripedBlocks}} to {{DFSTestUtils}} so the new reader tests can
use them. [~jingzhao] Let me know if that move looks OK to you.
> Erasure coding: pread from files in striped layout
