Hairong Kuang updated HDFS-1481:
--------------------------------
Attachment: trunkValidateUpload.patch
This patch calculates checksum when NameNode download image from Secondary or
Checkpointing NameNode. If the calculated checksum does not match the one
supposed to be, it fails the image transfer.
> NameNode should validate fsimage before rolling

> We had an incident that the fsimage at secondary NameNode was truncated but
> got uploaded to the primary NameNode. The primary NameNode simply rolled the
> image without checking its integrity, therefore causing the fsimage to
> corrupt. The primary NameNode should check the new image's integrity before
> rolling fsimage.
