hadoop cluster Unable to start standby Namenode

Question

we have HDP Hadoop cluster with two name-node services ( one active name-node and the secondary is the standby name-node )

due of unexpected electricity failure , the standby name-node failed to start with the flowing exception , while the active name-node starting successfully

    java.io.IOException: Failed to load FSImage file, see error(s) above for more info.

we can see from above exception - `Failed to load image from FSImageFile` , and seems it is as results of when machine failed because unexpected shutdown

as I understand one of the options to recover the standby name-node could be with the following procedure:

1. Put Active NN in safemode

    sudo -u hdfs hdfs dfsadmin -safemode enter

2. Do a savenamespace operation on Active NN

    sudo -u hdfs hdfs dfsadmin -saveNamespace

3. Leave Safemode

    sudo -u hdfs hdfs dfsadmin -safemode leave

4. Login to Standby NN

5. Run below command on Standby namenode to get latest fsimage that we saved in above steps.

    sudo -u hdfs hdfs namenode -bootstrapStandby -force

we glad to receive any suggestions , or if my above suggestion is good enough for our problem
