Steve Loughran commented on HDFS-3859: -------------------------------------- Isn't MD5 overkill? Can't a good CRC (like TCP Jumbo Frames uses) suffice? > QJM: implement md5sum verification > ---------------------------------- > > Key: HDFS-3859 > URL: https://issues.apache.org/jira/browse/HDFS-3859 > Project: Hadoop HDFS > Issue Type: Sub-task > Affects Versions: QuorumJournalManager (HDFS-3077) > Reporter: Todd Lipcon > Assignee: Todd Lipcon > > When the QJM passes journal segments between nodes, it should use an md5sum > field to make sure the data doesn't get corrupted during transit. This also > serves as an extra safe-guard to make sure that the data is consistent across > all nodes when finalizing a segment. -- This message is automatically generated by JIRA.
