NameNode should validate fsimage before rolling -----------------------------------------------
Key: HDFS-1481 URL: https://issues.apache.org/jira/browse/HDFS-1481 Project: Hadoop HDFS Issue Type: Improvement Components: name-node Affects Versions: 0.22.0 Reporter: Hairong Kuang Assignee: Hairong Kuang Fix For: 0.22.0 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
