If I want to configure my HiveServer2 (we use selfmade hadoop enviroment) to use Kerberos authentication it's require a secure hadoop envoriment too?
What I mean:
after I installed the kerberos I want to secure my Hiveserver2, but first I have to secure my hdfs, hadoop core-conf, mapred etc.. or not?
I hope it make sense, thank your for the help!
In order to kerborize hive server 2, It is must to kerborize all other hadoop services(for example hdfs, yarn etc) as well. I don't know what is the meaning of selfmade hadoop environment. You better use cloudera manager(CDH) or ambari server(Hortonworks) to enable kerberos for your hadoop services.
