HI We are currently trying to restart the HDFS name nodes in our cluster (HA). It seems that we are not able to start them. The process of restarting the node takes a long time until it finally fail with the following output on AMBARI:

@Koffi 

Yes you obviously cannot run safe mode when the namenodes are down

I can see the JN and ZKFC are all up can you run the below command on the last known good Namenode nn01 hopping you are running it as root

su -l hdfs -c "/usr/hdp/current/hadoop-hdfs-namenode/../hadoop/sbin/hadoop-daemon.sh start namenode"

If nn01 starts without any issue then run the same command on nn02 else share the logs from nn01

@Sheltoni have tried to do the first step (hdfs dfsadmin -safemode enter) but i am getting the following error:

 

 

safemode: Call From XX-XXX-XX-XXXX.XXXXX.XX/XX.X.XX.XX to XX-XXX-XX-XXXX.XXXXX.XX:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused
