Subject [jira] [Created] (HDFS-3878) Add an administrative command to download finalized edit log segments from the NN

Aaron T. Myers created HDFS-3878:
------------------------------------

             Summary: Add an administrative command to download finalized edit log segments
from the NN
                 Key: HDFS-3878
                 URL: https://issues.apache.org/jira/browse/HDFS-3878
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: hdfs client, name-node
    Affects Versions: 2.0.0-alpha
            Reporter: Aaron T. Myers


Similarly to the `hdfs dfsadmin -fetchImage' command added in HDFS-2941, it would be nice
to have an admin command capable of fetching edit log segments. This could be useful, for
example, for use in a script designed to back up the NN on-disk metadata.
