Description

On the last step "Start all" on enabling HA below happens:

"RemoteException": {
"exception": "RetriableException",
"javaClassName": "org.apache.hadoop.ipc.RetriableException",
"message": "org.apache.hadoop.hdfs.server.namenode.SafeModeException:
Cannot set permission for /ats/done. Name node is in safe mode.\nThe reported
blocks 675 needs additional 16 blocks to reach the threshold 0.9900 of total
blocks 697.\nThe number of live datanodes 20 has reached the minimum number 0.
Safe mode will be turned off automatically once the thresholds have been
reached."
}
}
This happens because NN is not yet out of safemode at the moment of ats start,
because DNs just started.
To fix this "stop namenodes" has to be triggered before "start all".
If this is done, on "Start all" it will be ensured that datanodes start prior
to NN, and that NN are out of safemode before ATS start.
