Based on the provided context, it appears that the hstore core tests are failing due to several exceptions being thrown. These exceptions are related to the creation, scheduling, and deletion of tasks in the HugeGraph database.

The specific errors are as follows:

1. IllegalArgumentException: Thrown when trying to delete an incomplete task.
2. IllegalArgumentException: Thrown when a HugeTask is created with a null id.
3. IllegalArgumentException: Thrown when a HugeTask is created with an id of invalid type.
4. NullPointerException: Thrown when a HugeTask is created with a null callable.
5. IllegalStateException: Thrown when a HugeTask is scheduled without setting a task type.
6. IllegalStateException: Thrown when a HugeTask is scheduled without setting a task name.
7. NotFoundException: Thrown when trying to access a task that has been deleted.

These errors are found in the testTask and testTaskWithFailure methods in the TaskCoreTest.java file.

Unfortunately, without more information, it's difficult to determine the exact cause of these test failures. The pull request #2414 and its potential impact on the hstore core tests, as well as the interaction between the pd-store and the hstore core tests, are not clear from the provided context.

If you could provide more details about the changes made in the pull request #2414, or any known issues or bugs in the pd-store that could have caused these test failures, it would be helpful in diagnosing the problem.

For more information about the purpose of the hstore core tests and the scenarios they cover, you can refer to the TaskCoreTest.java file in the incubator-hugegraph repository.

I hope this information is helpful. If you have any further questions or need more assistance, please don't hesitate to ask.

• Clearing the cache before each test allows all tests in MultiGraphsTest to pass, but other tests fail extensively.
• The NPE tests in HgStoreClient occur because the HugeGraph parameter passed during the construction of HugeVertex or HugeEdge is null (the store module cannot obtain the graph object instance).
• Tests related to OLAP in VertexCoreTest: Not adapted yet.
• Tests related to page in VertexCoreTest and EdgeCoreTest: Inconsistency in the definition of position between RocksDB scan iterator and Hstore.
• Some RamTableTest cases: The ramtable feature is not supported by the hstore backend.
