-----------------------------------

             Summary: Expected Exception when building Row with logical types 
with Invalid input 
                 Key: BEAM-9887
                 URL: https://issues.apache.org/jira/browse/BEAM-9887
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-core
            Reporter: Rahul Patwari
            Assignee: Rahul Patwari


schema.logicaltypes.FixedBytes logical type expects an argument - the length of 
the byte[].

When an invalid input(length < expectedLength) value is provided while building 
the Row with FixedBytes logical type, IllegalArgumentException is expected. 
But, the Exception is not thrown.

 

Schema schema = Schema.builder().addLogicalTypeField("char", 
FixedBytes.of(10)).build();
byte[] byteArray = \{1, 2, 3, 4, 5};
Row row = Row.withSchema(schema).withFieldValue("char", byteArray).build();
System.out.println(Arrays.toString(row.getLogicalTypeValue("char", 
byte[].class)));

 

The above code print "[1, 2, 3, 4, 5]" with length 5, whereas the expected 
length of FixedBytes is 10.
