-----------------------------------
Description:
There is a spurious error when stopping a secure datanode.
{code}
# hdfs --daemon stop datanode
cat: /var/run/hadoop/hdfs//hadoop-hdfs-root-datanode.pid: No such file or directory
WARNING: pid has changed for datanode, skip deleting pid file
cat: /var/run/hadoop/hdfs//hadoop-hdfs-root-datanode.pid: No such file or directory
WARNING: daemon pid has changed for datanode, skip deleting daemon pid file
{code}
The error appears benign. The service was stopped correctly.
