> If a user _does not_ have HDFS write permissions to the _default_ databas=
e, and attempts to create a table in a _private_ database to which the user=
 _does_ have permissions using CREATE TABLE AS SELECT from a table in the d=
efault database, the following happens:
> {code}
> use default;
> create table grisha.blahblah as select * from some_table;
> FAILED: SemanticException 0:0 Error creating temporary folder on: hdfs://=
nn.example.com/user/hive/warehouse. Error encountered near token 'TOK_TMP_F=
ILE=E2=80=99
> {code}
> I've edited this issue because my initial explanation was completely bogu=
s. A more likely explanation is in https://github.com/apache/hive/commit/16=
14314ef7bd0c3b8527ee32a434ababf7711278
> {code}
>  -                fname =3D ctx.getExternalTmpPath(
>  +                fname =3D ctx.getExtTmpPathRelTo( =20
>     // and then something incorrect happens in getExtTmpPathRelTo()
> {code}
> In any event - the bug is that the location chosen for the temporary stor=
age is not in the same place as the target table. It should be same as the =
target table (/user/hive/warehouse/grisha.db in the above example) because =
this is where presumably the user running the query would have write permis=
sions to.
