[jira] [Work logged] (HDFS-16547) [SBN read] Namenode in safe mode should not be transfer to observer state

     [ https://issues.apache.org/jira/browse/HDFS-16547?focusedWorklogId=758400&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-758400 ]

    Worklog Time Spent: 10m 
      Work Description: tomscut opened a new pull request, #4201:
URL: https://github.com/apache/hadoop/pull/4201

   JIRA: HDFS-16547.
   
   Currently, when a Namenode is in safemode(under starting or enter safemode manually), we can transfer this Namenode to Observer by command. This Observer node may receive many requests and then throw a SafemodeException, this causes unnecessary failover on the client.
   
   So Namenode in safe mode should not be transfer to observer state.
