Hi,
The primary namenode of my HA cluster using HDP2.6 goes into safemode daily due to "Namenode last checkpoint". The default dfs.namenode.checkpoint.period is 6 hours while https://hadoop.apache.org/docs/r2.4.1/hadoop-project-dist/hadoop-hdfs/hdfs-default.xml says the default is 1 hour. Manually updating this property to 1 hour does not make the alert go away. Any idea is highly appreciated. Thanks.
