To enable query vectorization, as Administrator you change hive-site.xml.
-
Navigate to the location of hive-site.xml and open the file in
a text editor.
-
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.
