Unexpected timezone

Error message

Unexpected timezone

What it means

Write-validation error in validateTimeZone: the timezone recorded in the re-read ORC footer differs from the writer's timezone (DWRF is exempt since it stores none). This flags files whose writer timezone metadata is inconsistent — potential corruption or a writer bug.

Solutions

1. Reproduce with orc.writer-validation enabled to confirm a writer bug
2. Ensure consistent JVM/coordinator timezone settings across the write job
3. Rewrite the affected data with validation passing
