Allen Wittenauer resolved HDFS-1029. ------------------------------------ Resolution: Fixed This is likely a stale issue. Closing. Reopen if you feel otherwise. > Image corrupt with number of files = 1 > -------------------------------------- > > Key: HDFS-1029 > URL: https://issues.apache.org/jira/browse/HDFS-1029 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Affects Versions: 0.20.1 > Reporter: Todd Lipcon > > Last week I recovered a corrupt namenode image that was completely sane > except that the "number of files" in the header was set to 1, rather than the > correct number (many million). The NN in question had been running for some > time, so I believe the 2NN uploaded this broken image as a checkpoint. After > this point, of course, no further checkpoints occurred, and the NN failed to > load its image upon restart. > Not sure how this happens - my only thought is that we may need to add > synchronization on the nsCount field in INodeDirectoryWithQuota, but that's a > long shot. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
