ns01 = HA( namenode194-active, namenode195-standby ) 
ns02 = HA( namenode196-active, namenode197-standby ) 
 
I was running on the server command 195
I was running the command(-safemode enter)  namenode194 server 
 
$HADOOP_PREFIX/bin/hdfs dfsadmin -safemode enter 
 
I was expecting to change safemode both namenode194 and namenode195 
 
However, only changes namenode195.
 
What's the problem?
