Subject [jira] [Created] (HDFS-6420) DFSAdmin#refreshNodes should be sent to both NameNodes in HA setup
Date Fri, 16 May 2014 18:37:15 GMT
Jing Zhao created HDFS-6420:
-------------------------------

             Summary: DFSAdmin#refreshNodes should be sent to both NameNodes in HA setup
                 Key: HDFS-6420
                 URL: https://issues.apache.org/jira/browse/HDFS-6420
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Jing Zhao
            Assignee: Jing Zhao


Currently in HA setup (with logical URI), the DFSAdmin#refreshNodes command is sent to the
NameNode first specified in the configuration by default. Users can use "-fs" option to specify
which NN to connect to, but in this case, they usually need to send two separate commands.
We should let refreshNodes be sent to both NameNodes by default.
