Checkpoints are corrupt

Error message

Checkpoints are corrupt

What it means

ORC stripe-reading error in StripeReader.readStripe: building row groups from the stripe's checkpoint/index data threw InvalidCheckpointException — the row-index checkpoints are inconsistent with the actual stream positions. Wrapped as 'Checkpoints are corrupt', indicating a corrupted or writer-buggy stripe index.

Solutions

1. Skip or rewrite the corrupted file
2. Verify with an external ORC tool whether the stripe index is valid
3. Report as a writer bug if the file was produced by Presto itself
