Hi all , In HDFS-903 - ( md5 verification of fsimage ) , with this change , Backupnode is downloading the image & edit files from namenode everytime since the difference in checkpoint time is always maintined b/w Namenode and Backupnode . This happens since Namenode is resetting its checkpoint time everytime since we are ignoring renewCheckpointTime and passing true explicitly to rollFsimage during endcheckpoint .. Also , though a proposal for using md5 to decide whether to download image is also mentioned , it doesnt seeem to be implemented .. Isn't this downloading of image everytime a problem or am I missing something ?
