Encode namespace identification info in image and edits headers ---------------------------------------------------------------
Key: HDFS-2032 URL: https://issues.apache.org/jira/browse/HDFS-2032 Project: Hadoop HDFS Issue Type: Improvement Components: name-node Affects Versions: Edit log branch (HDFS-1073), 0.23.0 Reporter: Todd Lipcon In HDFS-2026, Sanjay suggested that we add the namespaceID and clusterID as part of the header information in image and edits files. We can then verify that the namespace info matches the VERSION info before loading any such file. This would prevent any accidental mixing of transactions between two clusters (either by virtue of HDFS bugs or by operational mistakes). -- This message is automatically generated by JIRA.
