Add an admin command to trigger an edit log roll

    Details

    • Type: New Feature New Feature
    • Status: Closed
    • Priority: Major Major
    • Resolution: Fixed
    • Affects Version/s: 2.0.0-alpha
    • Fix Version/s: 2.0.2-alpha
    • Component/s: namenode
    • Labels:

    • Hadoop Flags:

    • Release Note:
      Introduced a new command, "hdfs dfsadmin -rollEdits" which requests that the active NameNode roll its edit log. This can be useful for administrators manually backing up log segments.

      Description

      This seems like it would also be helpful outside of the context of HA, but especially so given that the standby can currently only read finalized log segments.

        Converted this to a top-level issue, since it's applicable outside of HA as well.

        Patch looks pretty good to me. Just a few little comments:

        1. I don't understand why this "if(...)" is necessary:
          if (isFromClient) {
            checkSuperuserPrivilege();
          }
          

          It's certainly the case that arbitrary clients should be super users, but when would a non-super user node be calling this method? I think it should be safe to always check for super user privileges.

        2. Should the rollEdits RPC be marked @Idempotent? I can't think of a case when calling it twice would be problematic.

        Is the 2NN's principal always considered a superuser? I think so, but just want to confirm.

        Makes sense.
