CM version : 5.5.1
CDH version: the latest version
as i have tested, some machines can't show up hdfs files by hdfs dfs -ls . it shows up wanrings like not set fs.default.
after get these messages, i am going to check core-site.xml in /etc/hadoop/conf. the result is if the core-site.xml is empty,then can't show up hdfs files. i have tested many machines, if the machine role is not zk, HDFS then the core-site.xml is empty, i need add contents in core-site.xml and hdfs-site.xml manually . this kind case doesn't happend in previous version.
who can give me some advises for this issue, since i don't want to add the contents in core-site and hdfs-site for so many machines.
