I tried decommissioning a large DataNode, through by excluding hosts. But when I added host in the settings HDFS -> CONFIGURATION -> SERVICE WIDE -> ADVANCED -> HDFS Service Environment Safety Valve (Safety Valve) for dfs_hosts_exclude.txt, the file dfs_hosts_exclude.txt is not created. I tried to restart the service but nothing happens, hosts are not added to the configuration.
Now I'm using Cloudera 5.15, on version 5.14 there was no problem with this.
