That `deleteData` flag is confusing. If you look at the metastore server's
code, you will see that there is another flag called isExternal generated from
the table type. For the query
```
create external table $tabName(c1 int COMMENT 'abc', c2 string)
stored as parquet
location '$tmpDir'
as select 1, '3'
```
I am not sure I understand what you mean by `Although we use the EXTERNAL
keyword, the table is still managed_table. The above statement could be wrong`.
Why it is still a managed_table?
