    Affects Versions: Edit log branch (HDFS-1073)
    Reporter: Todd Lipcon
    Assignee: Todd Lipcon
    Fix For: Edit log branch (HDFS-1073)

    Attachments: hdfs-2027.txt


    Found this small bug while testing multiple NNs under failure conditions on the 1073 branch. When the 2NN calls getEditLogManifest(), it expects a list of finalized logs. In the case that one of the edit log directories had failed and recovered, there would be some txid for which there was an edit_N_inprogress and an edits_N-M (finalized). The edit log manifest needs to see the finalized one when it exists.
