/etc/hadoop/* directory and /var/run/cloudera-scm-agent/process/* directory

    Recently,I'm learning CDH5,I'm not very understand that the relation between /etc/hadoop/* directory and /var/run/cloudera-scm-agent/process/* directory.And Idon't kown that who the two directory are in the first ,who last.
    I kown that the  /var/run/cloudera-scm-agent/process/* directory are rebuild with the services start every time. And I also read the post "How Does Cloudera Manager Work?".
So,please help me to answer it,thanks.

/etc/hadoop/*
这个应该是源码目录，hadoop原生都是这个目录的，也就是源码和一些包都在这个目录的
另外一个应该是cloudera 增加的，可能是运行有关的
