Lohit Vijayarenu commented on HADOOP-3980:
------------------------------------------
We saw a case where local disk was corrupt and we were unable to read edits
from the disk. We used to hit Input/Output error while reading the edits
midway. SecondaryNameNode pulls fsimage,edits and it has to make sure we got
all of the bytes. One way is to make sure the file size matches as expected.
> SecondaryNameNode should validate the downloaded files.
