Create JAAS configuration files
  1. Create the following JAAS configuration files on the HBase Master, RegionServer, and HBase client host machines.

    These files must be created under the $HBASE_CONF_DIR directory:

    where $HBASE_CONF_DIR is the directory to store the HBase configuration files. For example, /etc/hbase/conf.

    • On each machine running an HBase server, create the hbase-server.jaas file under the /etc/hbase/conf directory. HBase servers include the HMaster and RegionServer. In this file, add the following content:

      Client {
      com.sun.security.auth.module.Krb5LoginModule required
      useKeyTab=true
      storeKey=true
      useTicketCache=false
      keyTab="/etc/security/keytabs/hbase.service.keytab"
      principal="hbase/$fully.qualified.domain.name";
      };                         
    • On HBase client machines, create the hbase-client.jaas file under the /etc/hbase/conf directory and add the following content:

      Client {
      com.sun.security.auth.module.Krb5LoginModule required
      useKeyTab=false
      useTicketCache=true;
      };                   

  2. Create the following JAAS configuration files on the ZooKeeper Server and client host machines.

    These files must be created under the $ZOOKEEPER_CONF_DIR directory, where $ZOOKEEPER_CONF_DIR is the directory to store the HBase configuration files. For example, /etc/zookeeper/conf:

    • On ZooKeeper server host machines, create the zookeeper-server.jaas file under the /etc/zookeeper/conf directory and add the following content:

      Server {
      com.sun.security.auth.module.Krb5LoginModule required
      useKeyTab=true
      storeKey=true
      useTicketCache=false
      keyTab="/etc/security/keytabs/zookeeper.service.keytab"
      principal="zookeeper/$ZooKeeper.Server.hostname";
      };                         
    • On ZooKeeper client host machines, create the zookeeper-client.jaas file under the /etc/zookeeper/conf directory and add the following content:

      Client {
      com.sun.security.auth.module.Krb5LoginModule required
      useKeyTab=false
      useTicketCache=true;
      };                 

  3. Edit the hbase-env.sh file on your HBase server to add the following information:

    export HBASE_OPTS ="-Djava.security.auth.login.config=$HBASE_CONF_DIR/hbase-client.jaas"
    export HBASE_MASTER_OPTS ="-Djava.security.auth.login.config=$HBASE_CONF_DIR/hbase-server.jaas"
    export HBASE_REGIONSERVER_OPTS="-Djava.security.auth.login.config=$HBASE_CONF_DIR/hbase-server.jaas"

    where HBASE_CONF_DIR is the HBase configuration directory. For example, /etc/hbase/conf.

  4. Edit zoo.cfg file on your ZooKeeper server to add the following information:

    authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider
    jaasLoginRenew=3600000
    kerberos.removeHostFromPrincipal=true
    kerberos.removeRealmFromPrincipal=true     
  5. Edit zookeeper-env.sh file on your ZooKeeper server to add the following information:

    export SERVER_JVMFLAGS ="-Djava.security.auth.login.config=$ZOOKEEPER_CONF_DIR/zookeeper-server.jaas"
    export CLIENT_JVMFLAGS ="-Djava.security.auth.login.config=$ZOOKEEPER_CONF_DIR/zookeeper-client.jaas"

    where $ZOOKEEPER_CONF_DIR is the ZooKeeper configuration directory. For example, /etc/zookeeper/conf.
