Hive#
Do not allow inserting into tables when the Hive type does not match the Presto type. Previously, Presto would insert data that did not match the table or partition type and that data could not be read by Hive. For example, Presto would write files containing
BIGINT
data for a Hive column type ofINT
.Add validation to CREATE TABLE and CREATE TABLE AS to check that partition keys are the last columns in the table and in the same order as the table properties.
Remove
retention_days

hive.orc.use-column-names=true
in your Hive catalog properties file.
