When starting an Impala minicluster on a local machine using '$IMPALA_HOME/bin/start-impala-cluster.py', by default there is no authorization service, e.g., Sentry or Ranger, enabled on this cluster. We could enable the Ranger service on an Impala minicluster by the following steps (assuming that we have already executed '$IMPALA_HOME/testdata/bin/run-all.sh').

  1. Execute '$IMPALA_HOME/testdata/bin/kill-ranger-server.sh'
  2. Execute 'source $IMPALA_HOME/bin/impala-config.sh'
  3. Execute '$IMPALA_HOME/buildall.sh -noclean -notests -ninja'
  4. Execute '$IMPALA_HOME/bin/create-test-configuration.sh -create_ranger_policy_db'
  5. Execute '$IMPALA_HOME/testdata/bin/run-ranger-server.sh'
  6. Execute '$IMPALA_HOME/testdata/bin/create-load-data.sh'
  7. Execute the following command. We note that the arguments passed into 'start-impala-cluster.py' could also be found at '$IMPALA_HOME/tests/authorization/test_ranger.py'. The first 4 arguments are passed to 'start-impala-cluster.py' directly and those surrounded by a pair of single quotation marks are passed to statestore, impalad, and catalogd, respectively.
