We are trying to set up a single node cloudera hadoop cluster having 16 GB as RAM on linux machine. We are setting up 5.4.2 version. Now when we check statistics post the installation and run the top command we find that only 1 -2 GB is available. when we trigger map reduce sample job - no memory is allocated to the job and so job doesnt run. Can you please let us know what should we do so that more memory is available Analysis of the top command cloudera takes 4-5 GB. mysql 6 GB.(external database to store the metastore) other services 2-3 GB. thus contributing to 13 GB out of 16

Hello, I have CDH 5.2 installed on a 2 node cluster. I also have an OpenLDAP server setup separately. I was successful in configuring Hive with LDAP. I've used the 'LDAP' protocol (ldap://hostname:389 and not ldaps://hostname:636). I'm trying to enable Sentry with Hive now. LDAP was configured with Hive as it seems to be a pre-requisite. I donot have Kerberos enabled. I'm have set sentry.hive.testing.mode to true in sentry-site.xml so that I can skip enabling kerberos for the time being. My question is: 1. Can sentry be enabled with ldap? or is ldaps required to enable sentry? 2. Could you please give me some documentation or links which will help me in enabling sentry for Hive? any or all sources will be helpful. Any information will be helpful. Thanks and Regards, Gaurav
