Upgrading Impala

This section describes how to upgrade Immpala without the MapR Installer.
  1. Upgrade the mapr-impala package on all Impala nodes in the cluster:
    $ sudo yum update mapr-impala
  2. In /opt/mapr/impala/impala-<version>/conf/env.sh, complete the following steps:
    1. Verify that the Statestore address is set to the address where you plan to run the statestore service.
      IMPALA_STATE_STORE_HOST=<IP address hosting statestore>
    2. Change the Catalog service address to the address where you plan to run the catalog service.
      CATALOG_SERVICE_HOST=<IP address hosting catalog service>

      Refer to Additional Impala Configuration Options for a list of other options that you can modify in env.sh.

  3. Verify that hive-site.xml has the following property configured on all nodes:
    <property>
    <name>hive.metastore.uris</name>
    <value>thrift://<metastore_server_host>:9083</value>
</property>
  4. To upgrade the statestore service, issue the following command:
    $ sudo yum update mapr-impala-statestore
  5. To upgrade the catalog service, issue the following command:
    $ sudo yum update mapr-impala-catalog
    NOTE: It is recommended (not required) that you install the catalog service on the same node as the statestore service.
  6. To upgrade the impala server, issue the following command:
    $ sudo yum update mapr-impala-server
  7. Run configure.sh to refresh the node configuration. 
    /opt/mapr/server/configure.sh -R
