Hi all,
Currently when the in-memory catalog is used, e.g. through `--conf
spark.sql.catalogImplementation=in-memory`, we can create a persistent
table, but inserting into this table would fail with error message "Hive
support is required to insert into the following tables..".
sql("create table t1 (id int, name string, dept string)") // OK
sql("insert into t1 values (1, 'name1', 'dept1')") // ERROR
This doesn't make sense for me, because this table would always be empty if
we can't insert into it, thus would be of no use. But I wonder if there are
other good reasons for the current logic. If not, I would propose to raise
an error when creating the table in the first place.
Thanks!
