> We removed two level access in PIG-847. However, there is another occurrence we miss in ResourceSchema.java:
> {code}
> if (type == DataType.BAG && fieldSchema.schema != null
> && !fieldSchema.schema.isTwoLevelAccessRequired()) {
> log.info("Insert two-level access to Resource Schema");
> FieldSchema fs = new FieldSchema("t", fieldSchema.schema);
> inner = new Schema(fs);
> }
> {code}
> Though by default schema.isTwoLevelAccessRequired is false, we shall not use this flag in Pig. User could set this flag in legacy UDF.
> Thanks Woody uncovered this.
