According to https://hive.apache.org/general/downloads/
"The Apache Hive Community has voted to declare the 3.x release line as End of Life (EOL). This means no further updates or releases will be made for this series.
We urge all Hive 3.x users to upgrade to the latest versions promptly to benefit from new features and ongoing support."
CDP 7.3.1 is still very much based on Hive 3.

When will Cloudera on base support Hive 4?
Thanks
