https://github.com/apache/spark/pull/16938
@cloud-fan @gatorsmile @tejasapatil As we discussed above, we have three
actions to do:
##### 1. CREATE TABLE ... (PARTITIONED BY ...) LOCATION path
*situation:path not exists*
Item | Before| After
------------ | ------------- | -----
spark(parquet with HiveExternalCatalog) | throw exception(path does not
exists) | ok
spark(parquet with InMemoryCatalog) | throw exception(path does not exists)
| ok
##### 2. CREATE TABLE ...(PARTITIONED BY ...) LOCATION path AS SELECT
*situation:path exists*
Item | Before| After
------------ | ------------- | -----
spark(parquet with HiveExternalCatalog) | throw exception(path already
exists) | ok
spark(parquet with InMemoryCatalog) | throw exception(path already exists)
| ok
##### 3. CREATE TABLE ... (PARTITIONED BY ...) AS SELECT ...
*situation:default warehouse table path exists*
Item | Before| After
------------ | ------------- | -----
spark(hive with HiveExternalCatalog) | ok | throw exception(path already
exists)
please help to confirm the actions above, if it is ok, situation 2 is this
PR going to resolve, and I will make another PR to resolve situation 1&3,
thanks~
