> Fix the SNN repeatedly checkpoint after fsimage transfer failure on one of
> the multiple NNs
> -------------------------------------------------------------------------------------------
>
> Key: HDFS-17821
> URL: https://issues.apache.org/jira/browse/HDFS-17821
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 3.5.0
> Reporter: caozhiqiang
> Assignee: caozhiqiang
> Priority: Major
> Labels: pull-request-available
>
> In our cluster with observer NNs, when the standby NN is doing a checkpoint
> and sending the fsimage to other NNs, if the sending fails of one NN due to
> network anomalies, NN restarts, or other exceptions, the standby will
> consider this Checkpoint as failed and does not update the
> lastCheckpointTime, and retry checkpoints.
> However, the active or observer NNs which successfully received the fsimage
> has update their lastCheckpointTime, and the NN which receive fsimage failed
> don't update its lastCheckpointTime, resulting in inconsistent
> lastCheckpointTime across the NNs. This causes subsequent checkpoints to
> repeatedly fail to send fsimage to part or all active or observer NNs,
> because they do not satisfy the DFS_NAMENODE_CHECKPOINT_PERIOD_KEY condition.
> Then the SNN will always failed to do checkpoint and repeat retry. I think
> that the SNN should consider the checkpoint successful and update its
> lastCheckpointTime if the fsimage transmission succeeds on at least half of
> the NNs.
