> Currently DFS can write multiple copies of image files but we do not automatically recover
from corrupted or truncated image files well. This jira intends to keep CRC for image file
records and Namenode should recover accurate image as long as data exists in one of the copies
(e.g. it should be ok to have non overlapping corruptions in the copies). Will add more details
in next comment.
