Migrate the HDP Configurations

Configurations and configuration file names have changed between HDP 1.3.2 (Hadoop 1.2.x) and HDP 2.4.2 (Hadoop 2.6). To upgrade to HDP 2.4.2, back up your current configuration files, download the new HDP 2.4.2 files, and compare. The following tables provide mapping information to make the comparison between releases easier.

To migrate the HDP Configurations

  1. Edit /etc/hadoop/conf/core-site.xml and set hadoop.rpc.protection from none to authentication.

    [Note]Note

    Hadoop lets cluster administrators control the quality of protection in the configuration parameter “hadoop.rpc.protection” in core-site.xml. It is an optional parameter in HDP 2.4.2. If not present, the default QOP setting of “auth” is used, which implies “authentication only”.

    Valid values for this parameter are: “authentication” : Corresponds to “auth” “integrity” : Corresponds to “auth-int” “privacy” : Corresponds to “auth-conf”

    The default setting is authentication-only because integrity checks and encryption are a performance cost.

  2. Copy your /etc/hcatalog/conf configurations to /etc/hive-hcatalog/conf and /etc/hive-webhcat as appropriate.

  3. Copy log4j.properties from the hadoop config directory of the companion files to /etc/hadoop/conf. The file should have owners and permissions similar to other files in /etc/hadoop/conf.

  4. Download the your HDP 2.4.2 companion files from Download Companion Files and migrate your HDP 1.x configuration.

  5. Copy these configurations to all nodes in your clusters.

    • /etc/hadoop/conf

    • /etc/hbase/conf

    • /etc/hcatalog/conf

    • /etc/hive/conf

    • /etc/pig/conf

    • /etc/sqoop/conf

    • /etc/flume/conf

    • /etc/mahout/conf

    • /etc/oozie/conf

    • /etc/zookeeper/conf

    [Note]Note

    Upgrading the repo using yum or zypper resets all configurations. Prepare to replace these configuration directories each time you perform a yum or zypper rmgrade.

  6. Review the following HDP 1.3.2 Hadoop Core configurations and the new configurations or locations in HDP 2.4.2.

    [Note]Note

    The hadoop.rpc.protection configuration property in core- site.xml needs to specify authentication, integrity and/or privacy. No value defaults to authentication, but an invalid value such as "none" causes an error.

  15. For a secure cluster, add the following properties to mapred-site.xml:

    <property>
     <name>mapreduce.jobhistory.principal</name>
     <value>jhs/_PRINCIPAL@$REALM.ACME.COM</value>
     <description>Kerberos principal name for the MapReduce JobHistory Server.
     </description>
    </property>
    
    </property>
     <name>mapreduce.jobhistory.keytab</name>
     <value>/etc/security/keytabs/jhs.service.keytab</value>
     <description>Kerberos keytab file for the MapReduce JobHistory Server.</description>
    </property> 
  16. For a secure cluster, you must also update hadoop.security.auth_to_local in core- site.xml to include a rule regarding the mapreduce.jobhistory.principal value you set in the previous step:

    RULE:[2:$1@$0](PRINCIPAL@$REALM.ACME.COM )s/.*/mapred/

    where PRINCIPAL and REALM are the kerberos principal and realm you specified in mapreduce.jobhistory.principal.

  17. Delete any remaining HDP1 properties in the mapred-site.xml file.

  18. Replace the default memory configuration settings in yarn-site.xml and mapred-site.xml with the YARN and MapReduce memory configuration settings you calculated previously.
