-----------------------------
Summary: Rolling upgrade won't finish if SBN is configured without
StandbyCheckpointer
Key: HDFS-6637
URL: https://issues.apache.org/jira/browse/HDFS-6637
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 3.0.0
Reporter: Dian Fu
In HA setup cluster, for rolling upgrade, the image file "fsimage_rollback" is
generated by StandbyCheckpointer thread of SBN. While if configuration
"dfs.ha.standby.checkpoints" is set false, there will be no StandbyCheckpointer
thread in SBN. This will lead to the rolling upgrade never finish.
