[jira] [Created] (ARROW-12487) [C++][Dataset] ScanBatches() hangs if there's an error during scanning

David Li created ARROW-12487:
--------------------------------

             Summary: [C++][Dataset] ScanBatches() hangs if there's an error during scanning
                 Key: ARROW-12487
                 URL: https://issues.apache.org/jira/browse/ARROW-12487
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
    Affects Versions: 4.0.0
            Reporter: David Li
            Assignee: David Li


Errors during scanning aren't properly reported, causing the iterator to hang forever.

This affects ScanBatches() and anything built on top of it (Python to_batches, TakeRows, etc)

Verified on the 4.0.0 RC
