Update Ranger Table Policies

Although the upgrade process makes no change to the location of external tables, if you moved tables during the upgrade process, you need to update/create HDFS Ranger policies, or use HDFS ACLs.

Set up access to external tables in HDFS using one of the following methods.

  • Set up a Hive HDFS policy in Ranger (recommended) to include the paths to external table data.
  • Put an HDFS ACL in place. Store the external text file, for example a comma-separated values (CSV) file, in HDFS that will serve as the data source for the external table.
