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 know the methods for accessing external tables in HDFS.

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.
