Github user gatorsmile commented on the issue:
https://github.com/apache/spark/pull/16938
Basically, the rules you proposed are
- When users specify the location in CT or CTAS (i.e., creating an external
table), we should create a new directory if not existed, or overwrite the
directory if already created.
- When users do not specify the location in CT or CTAS (i.e., creating a
manged table), we should create a new directory if not existed. If the
directory already exists, we should issue the error.
Is my understanding right?
