https://github.com/apache/spark/pull/14894
@srowen I checked DDLSuite.scala, the case "Create Database using Default
Warehouse Path" is used to test the default "spark-warehouse" setting. In the
doc, the default path should be "("user.dir")/spark-warehouse". I prefer to
keep the path, just remove it after finish the case manually.
For the "tempDir" in DDLSuit.scala, I confirm it is point to the temporary
path. It is safe enough.
When check the cases in DDLSuite.scala, I found the "spark-warehouse" is
always created by the UT frame. At the final, the directory is empty and it
will not negative impact on the UT. I tried to set the WAREHOUSE_PATH of
SQLConf to redirect to the temporary path, but failed. May I delete the
"spark-warehouse" in function afterEach()? Or could you please give me some
suggestion? Thanks a lot!
