https://community.cloudera.com/t5/Support-Questions/How-to-restrict-a-hadoop-user-to-use-a-hadoop-commands-like/m-p/211253#M173195 <P>Hi, </P><P>I'm looking for a possible way to restrict user to use some Hadoop commands. In other words, how to disable a Hadoop command for particular users? Below is the scenario :- </P><PRE>[foo@bdlhdptst01 ~]$ whoami foo [foo@bdlhdptst01 ~]$ hadoop fs -ls /user/foo Found 1 item -rwxrwxrwx 3 foo hadoop 0 2018-05-21 05:56 /user/foo/test.txt </PRE><P>For example, I don't want a user "foo" to run the below "chmod" command which he owns (shown above) </P><PRE>[foo@bdlhdptst01 ~]$ hadoop fs -chmod 700 /user/foo/test.txt </PRE><P>If we can disable a command in OS level (Linux) for a user, I believe we can disable the same in Hadoop as well. Any suggestions would be highly appreciated! </P><P><STRONG>Note: Without using ACLs, </STRONG><STRONG>Ranger or Kerberos</STRONG></P><P>Regards, </P><P>Shesh Kumar</P> Sat, 04 Aug 2018 20:40:51 GMT sheshk11 2018-08-04T20:40:51Z
