> The pendingDatanodeMessage issue mentioned here strikes me as a bit risky. ... I'm not following. The issue described from HDFS-2737 says that "if the active NN is not rolling its logs periodically ... many datanode messages \[will\] be queued up in the PendingDatanodeMessage structure". Certainly it is bad if we don't have a way to ensure that the logs are rolled regularly. But HDFS-14378 just proposes making the ANN roll its own edit logs, instead of relying on the SbNN to roll them. I don't see the risk -- we are still ensuring that the logs are rolled periodically, just triggered by the ANN itself instead of the SbNN. -- This is an automated message from the Apache Git Service.
