Hadoop demons don't stop

I am trying to stop the daemon processes in hadoop on. / stop -all.sh script, but it gives the following message:

no jobtracker to stop localhost: no tasktracker to stop stop naming ban localhost: no datanode to stop localhost: no secondarynamenode to stop

I tried to check if chaop works after that using jps and it showed:

27948 SecondaryNameNode 27714 NameNode 28136 TaskTracker 27816 DataNode 28022 JobTracker 8174 Jps

That is, it correctly launches all demons. I also checked hasoop dfs -ls / just to see if I can connect to hdfs. He works.

I run the stop -all.sh script by the value of the supergroup user, there are no problems with permissions.
