GM @amoeba it is pretty much standard code that i got from the example and
I tried using 16.0.1, 16.0.0 and 15.0.1
String uri = parquetFile.toURI().toString();
ScanOptions options = new ScanOptions(/* batchSize */ 32768);
try (BufferAllocator allocator = new RootAllocator();
DatasetFactory datasetFactory = new
FileSystemDatasetFactory(allocator, NativeMemoryPool.getDefault(),
FileFormat.PARQUET, uri);
Dataset dataset = datasetFactory.finish();
Scanner scanner = dataset.newScan(options);
ArrowReader reader = scanner.scanBatches()) {
int batchCount = 0;
while (reader.loadNextBatch()) {
try (VectorSchemaRoot root = reader.getVectorSchemaRoot()) {
//function to create csv data
createCSV()
}
it fails when it tries to load the second batch.
