问题
When using Cloudera Manager I can access to the hdfs-site.xml file via :
Cloudera Manager > Cluster > HDFS > Instances > (NameNode, for example)> Processes
COnfiguration Files > hdfs-site.xml
Then the URL points to :
http://quickstart.cloudera:7180/cmf/process/8/config?filename=hdfs-site.xml
Is this file accessible directly via the file system and if yes, where is it located
回答1:
The configurations set in the Cloudera Manager are stored in the Cloudera Manager Database. They are not persisted in the configuration files as in for other distributions.
On starting the service, the related configurations are passed as runtime configurations to the Cloudera Agent running on the node where the service is to be started. These passed on configurations are stored in the runtime directory /var/run/cloudera-scm-agent/ of the agent.
