> Drop Dataverse Throws Resource Not Exists Exception
> ---------------------------------------------------
>
> Key: ASTERIXDB-2329
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2329
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: MTD - Metadata
> Reporter: Chen Luo
> Assignee: Murtadha Hubail
> Priority: Critical
>
> Previously I constantly encounter ResourceNotExistException when dropping
> dataverse. After some digging, I found the problem is caused as follows:
> 1. Start a fresh AsterixDB, and create dataverse/dataset.
> {code}
> drop dataverse test if exists;
> create dataverse test;
> use test;
> create type testType as{id:int};
> create dataset testDS(testType) primary key id;
> create primary index primaryIdx on testDS;
> {code}
> 2. Insert a record.
> {code}
> use test;
> insert into testDS{"id":1};
> {code}
> 3. Shutdown AsterixDB.
> 4. Re-start AsterixDB.
> 5. Drop and recreate the same dataverse.
> {code}
> drop dataverse test if exists;
> create dataverse test;
> use test;
> create type testType as{id:int};
> create dataset testDS(testType) primary key id;
> create primary index primaryIdx on testDS;
> {code}
> Now we can get an exception:
> {code}
> org.apache.hyracks.api.exceptions.HyracksDataException: HYR0055: Resource
> does not exist for storage/partition_1/test/testDS/0/testDS

> The root cause seems to be that drop dataverse in step 5 is not executed
> properly. It suppose to drop all datasets, all indexes associated with the
> dataverse. However, line 1253 of QueryTranslator returns empty index list
> (MetadataManager.getDatasetIndexes returns at line 292 because the dataset
> does not exist in cache), which causes indexes are not dropped properly.
