ICEBERG_INVALID_METADATA

ICEBERG_INVALID_METADATA

Error message

Cannot read manifest files. Manifests may be written by a newer Iceberg version.

What it means

In PartitionTable.getPartitions, an exception while reading or parsing manifest entries (data files written by a newer Iceberg version with unknown fields/features) is converted to this error, meaning the manifest content cannot be interpreted to compute partition stats.

Solutions

1. Upgrade Presto to a version compatible with the Iceberg version that wrote the manifests
2. Rewrite manifests with a compatible writer (rewrite_manifests) to the supported spec
