Failed to drop view ${identifier}

Error message

Failed to drop view ${identifier}

What it means

dropView() wraps a Thrift TException from the Hive Metastore in a RuntimeException with this message when the view drop fails at the RPC level. A nonexistent view returns false instead; this exception signals a metastore communication or server-side failure.

Solutions

1. Check metastore connectivity and health; inspect the wrapped TException cause.
2. Retry the drop with backoff for transient RPC failures.
3. Confirm Hive client/server compatibility.
4. Verify the view exists and is an Iceberg view via Hive if the failure persists.

Example fix

// before
catalog.dropView(viewId);
// after
try {
  catalog.dropView(viewId);
} catch (RuntimeException e) {
  throw new RuntimeException("View drop failed at metastore: " + viewId, e.getCause());
}

if (!catalog.viewExists(viewId)) {
  return false; // nothing to drop
}

try {
  catalog.dropView(viewId);
} catch (RuntimeException e) {
  if (e.getCause() instanceof TException) {
    // retry with backoff
  }
  throw e;
}

When it happens

Trigger: Calling catalog.dropView(identifier) and the metastore throws TException during the drop — connection failure, protocol error, or metastore internal error.

Common situations: Metastore down or unreachable; Thrift version mismatch between client and server; metastore backend database errors while deleting the view entry.
