---------------------------------
Summary: 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.
