'hadoop cluster: namenode stopping service after format the hdfs
After successfully formatted I get:
2022-05-04 15:49:01,051 INFO namenode.FSNamesystem: Stopping services started for active state
2022-05-04 15:49:01,051 INFO namenode.FSNamesystem: Stopping services started for standby state
then when I run
noor@m1:~$ start-all.sh
WARNING: Attempting to start all Apache Hadoop daemons as noor in 10 seconds.
WARNING: This is not a recommended production deployment configuration.
WARNING: Use CTRL-C to abort.

Starting resourcemanager
Starting nodemanagers
noor@m1:~$ jps

and in datanode at m2:
noor@m2:~$ jps
2165 Jps

As you see datanode at m2 does not run
