Error message

Invalid Hive object for %s.%s

What it means

doCommit maps Hive metastore's InvalidObjectException to Iceberg's ValidationException with "Invalid Hive object for database.viewName". The metastore rejected the view metadata as invalid — bad table type, invalid parameters, schema/field issues, or naming violations — so the commit never reached the concurrency stage.

Solutions

1. Validate the view and column names against Hive identifier rules (alphanumerics/underscore) and rename if needed.
2. Check the schema for types or constructs unsupported by your HMS version and simplify or upgrade the metastore.
3. Inspect the chained cause (getCause()) for HMS's specific validation message and fix the offending field/parameter.
4. Remove custom/hand-written table parameters that violate HMS validation and set properties through Iceberg APIs only.

Example fix

// before: column name with invalid character for HMS
view.updateSchema().addColumn("order amount", Types.IntegerType.get()).commit();
// after
view.updateSchema().addColumn("order_amount", Types.IntegerType.get()).commit();

// Validate names before committing
String name = identifier.name();
if (!name.matches("[A-Za-z0-9_]+")) {
  throw new IllegalArgumentException("View name contains characters HMS rejects: " + name);
}
for (Types.NestedField f : schema.columns()) {
  if (!f.name().matches("[A-Za-z0-9_]+")) {
    throw new IllegalArgumentException("Column name not HMS-safe: " + f.name());
  }
}

try {
  view.updateSchema().addColumn(...).commit();
} catch (ValidationException e) {
  if (e.getMessage() != null && e.getMessage().startsWith("Invalid Hive object")) {
    // inspect e.getCause() (InvalidObjectException) for HMS's specific complaint
  } else { throw e; }
}

When it happens

Trigger: Committing view create/update when HMS throws InvalidObjectException, e.g., malformed table parameters, invalid characters in names, schema fields HMS cannot represent, or metadata that violates HMS validation rules.

Common situations: View names or column names with characters HMS disallows; schema types/fields incompatible with the Hive metastore version; corrupted or hand-crafted parameters being persisted; metastore version mismatch with stricter validation.

Understand the failure class

Background: Schema validation failed / invalid input schema: payload rejected because its shape doesn't match the expected schema — this error's family across 28 libraries.
