https://community.cloudera.com/t5/Support-Questions/How-to-restrict-a-hadoop-user-to-use-a-hadoop-commands-like/m-p/211255#M173197 <P>What are you trying to achieve with this? If it is a non-kerberos cluster, if you have network access to the cluster, it will still leave holes for a user to go in as any other user. Just blocking hadoop fs access is not possible (unless you block full hadoop command) and it is not going to help</P><P>You need to go with Kerberos for security and authentication AND then ranger or ACLs for authorization. </P> Mon, 06 Aug 2018 01:45:04 GMT ravi1 2018-08-06T01:45:04Z
