Hi @Wenchen Fan <cloud0...@gmail.com> Thanks for your response. I believe we have not had enough time to "DISCUSS" this matter.
Currently in order to make Spark take advantage of Hive, I create a soft link in $SPARK_HOME/conf. FYI, my spark version is 3.4.0 and Hive is 3.1.1 /opt/spark/conf/hive-site.xml -> /data6/hduser/hive-3.1.1/conf/hive-site.xml This works fine for me in my lab. So in the future if we opt to use the setting "spark.sql.legacy.createHiveTableByDefault" to False, there will not be a need for this logical link.? On the face of it, this looks fine but in real life it may require a number of changes to the old scripts. Hence my concern. As a matter of interest has anyone liaised with the Hive team to ensure they have introduced the additional changes you outlined?
