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.
