Enable vectorization

To enable query vectorization, disabled by default, as Administrator you change hive-site.xml.

  1. Navigate to the location of hive-site.xml and open the file in a text editor.
  2. Enable query vectorization by enabling vectorized execution in hive-site.xml.
    hive.vectorized.execution.enabled=true
    After you issue a query, Hive examines the query and the data to determine whether vectorization can occur. If not, Hive executes the query with vectorization disabled.
