Description

Run the following unittest:

  @Test
  public void testParquetReaderCleanupNPE() throws Exception {
    test("SELECT * FROM cp.`parquet2/decimal28_38.parquet`");
  }

Following is the output:

Exception (no rows returned): org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR: 

Fragment 0:0

[Error Id: 49db6650-8f62-4c5c-b9dc-3f5d6a4413a0 on localhost:31010].  Returned in 407ms.

org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR: 

Fragment 0:0

Ideally in this case we should get the following query error:

Exception (no rows returned): org.apache.drill.common.exceptions.UserRemoteException: UNSUPPORTED_OPERATION ERROR: Decimal data type is disabled. 
As of this release decimal data type is a beta level feature and should not be used in production 
Use option 'planner.enable_decimal_data_type' to enable decimal data type
