Yang Yun commented on HDFS-15104:
---------------------------------
For the block, it's missing. But for the file, it's corrupt as fsck show.
I open this for it's different behavior between 3.3 and 2.6, the code of 2.6 is
as below. it thinks missing in 2.6 code. Did we intentionally modify its
behavior?
final boolean isCorrupt = numCorruptNodes == numNodes;
> If block is not reported by any Datanode, the flag corrupt of BlockLocation
> should be marked as true.
