> Project: Apache AsterixDB
> Issue Type: Bug
> Components: MTD - Metadata, STO - Storage
> Reporter: Ian Maxon
> Assignee: Ian Maxon
> Priority: Major
> Labels: triaged
>
> On case-insensitive filesystems, our storage properly compares directories
> according to how the case-sensitivity of the filesystem. However, this isn't
> propagated up to the DDL statements. Therefore a set of statements like this:
> {code:java}
> CREATE DATAVERSE test;
> CREATE DATASET foo(fooType) primary key id;
> CREATE DATAVERSE Test;
> CREATE DATASET foo2(fooType) primary key id;
> DROP DATAVERSE test;
> DROP DATAVERSE Test;
> {code}
> Will end up with the last drop being unable to find the files to delete with
> a Hyracks exception, because the first already deleted them.
>
> We should at the very least warn when creating a dataverse that already seems
> to exist due to the case insensitivity of the filesystem.
