Right now there's no way of knowing the txid of the downloaded image. I think the best solution is to add a header like: I added a Content-Disposition header in all cases of downloading an fsimage or edits file so that third-party HTTP requests will work, and added a Hadoop-specific header in the case of fetching the latest image, so as to avoid having to parse the Content-Disposition header. > Add an administrative command to download a copy of the fsimage from the NN > --------------------------------------------------------------------------- > > Key: HDFS-2941 > URL: https://issues.apache.org/jira/browse/HDFS-2941 > Project: Hadoop HDFS > Issue Type: New Feature > Components: hdfs client, name-node > Affects Versions: 0.24.0 > Reporter: Aaron T.
