… exceptions occur Sometimes it will checkpoint repeatedly on our cluster with multiple SNNS（hdfs verison ：3.2.1）. We check the codes， and find that it will send fsimage file to all other namenode. When it sends the fimage file to the other snns， it will fail because of other snns will refuse to receive the file。 It will affect the whole login of checkpointing。For example， we check the result of transfering fsimage to snn by feature‘s geting method， and it will throw the IOException and don't update the lastUploadTime and the lastCheckpointTime，then it will checkpoint repeatedly. I think that the snn node should only transfers the fsimage to active nn , so it is ok if sending the fsiamge to the other nodes unsuccessfully. ### Description of PR ### How was this patch tested? ### For code changes: - [ ] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799.
