Grisha Trubetskoy updated HIVE-11427:
-------------------------------------
Description:
If a user _does not_ have HDFS write permissions to the _default_ database, 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 default
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_FILE’
{code}
I've edited this issue because my initial explanation was completely bogus. A
more likely explanation is in
https://github.com/apache/hive/commit/1614314ef7bd0c3b8527ee32a434ababf7711278
{code}
- fname = ctx.getExternalTmpPath(
+ fname = ctx.getExtTmpPathRelTo(
// and then something incorrect happens in getExtTmpPathRelTo()
{code}
In any event - the bug is that the location chosen for the temporary storage 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 permissions to.
