Summary: Avoid affecting the overall logic of checkpoint when I/O
exceptions occur
Key: HDFS-17244
URL: https://issues.apache.org/jira/browse/HDFS-17244
Project: Hadoop HDFS
Issue Type: New Feature
Affects Versions: 3.2.1
Reporter: liying

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.
