             Summary: Checkpointing should use HTTP POST or PUT instead of GET-GET to send merged fsimages
                 Key: HDFS-3405
                 URL: https://issues.apache.org/jira/browse/HDFS-3405
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 1.0.0
            Reporter: Aaron T. Myers


As Todd points out in [this comment|https://issues.apache.org/jira/browse/HDFS-3404?focusedCommentId=13272986&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13272986], the current scheme for a checkpointing daemon to upload a merged fsimage file to an NN is to issue an HTTP get request to tell the target NN to issue another GET request back to the checkpointing daemon to retrieve the merged fsimage file. There's no fundamental reason the checkpointing daemon can't just use an HTTP POST or PUT to send back the merged fsimage file, rather than the double-GET scheme.
