Signing on and running queries

You need to meet certain prerequisites before attempting to use token-based authentication for running Hive or Impala queries: local prerequisites for running queries from a node in the cluster, or remote prerequisites for running queries from outside the cluster.

Local prerequisites

  • Knox is running on the cluster.

Remote prerequisites

  • A JDBC/ODBC driver runs remotely on a server, for example the Tableau server.
  • A thin client connects to the remote server and serves up a UI for entering a user name and password to connect.
