Code in setup_cluster.sh related to creating users (via useradd and via ldap/ipa) has been removed. Checking rhs-hadoop-install-1_32-1.el6rhs.noarch Scripts automating non-ldap user setup: /usr/share/rhs-hadoop-install/bin/add_users.sh /usr/share/rhs-hadoop-install/bin/add_groups.sh are still shipped in the package. This contradicts the statement in comment 3 and our current documentation. Note: this is the same kind of problem as with BZ 1105149: it's not a good idea to ship unused code to the customers. I forgot about add_users.sh and add_groups.sh -- good find! I've moved these to scripts to the archive github folder. I want to preserve the "user adding/ldap-ipa" code in setup_cluster. What is recommend practice here? I've commented out the call to the related functions and added a comment in these function that they are not used in Denali. But, I'd still like the code to be available if we decide, post-Denali, to automate some aspects of Hadoop user creation. I have deleted all code related to creating the hadoop users. Fixed in version 1.34. Tested with: rhs-hadoop-install-1_34-1.el6rhs.src.rpm (https://brewweb.devel.redhat.com/buildinfo?buildID=371877) comparing with older rhs-hadoop-install-1_33-1.el6rhs.src.rpm (https://brewweb.devel.redhat.com/buildinfo?buildID=371149) In file setup_cluster.sh was previously present "setup_users" function, flags SETUP_LDAP and SETUP_USERS and other stuff related to this. This function is now completely gone and flags used in it too. Arguments --deploy-ldap-srv and --local-auth which setted up mentioned flags are not accepted anymore. Files add_users.sh and add_groups.sh are not there and there is no reference to them. This issue is fixed -> VERIFIED.

Description of problem: ======================= used rhs-hadoop-install - setup_cluster.sh for hadoop set up without creating required user first. Scripts has created users but hose users do not have same uid always.
