> There are some shortcomings of the hudi-test-suite which would be good to fix:
> 1. When doing repeated testing with the same DAG, the input and output 
> directories need to be manually cleaned. This is cumbersome for repeated 
> testing.
> 2. When running a long test, the input data generated by older DAG nodes is 
> not deleted and leads to high file count on the HDFS cluster. The older files 
> can be deleted once the data has been ingested.
> 3. When generating input data, if the number of insert/update partitions is 
> less than spark's default parallelism, a number of empty avro files are 
> created. This also leads to scalability issues on the HDFS cluster. Creating 
> large number of smaller AVRO files is slower and less scalable than single 
> AVRO file.
> 4. When generating data to be inserted, we cannot control which partition the 
> data will be generated for or add a new partition. Hence we need a 
> start_offset parameter to control the partition offset.
> 5. BUG: Does not generate correct number of insert partitions as partition 
> number is chosen as a random long. 
> 6. BUG: Integer division used within Math.ceil in a couple of places is not 
> correct and leads to 0 value.  Math.ceil(5/10) == 0 and not 1 (as intended) 
> as 5 and 10 are integers.
>  
> 1. When generating input data,
