Alexey Kudinkin commented on HUDI-3348:
---------------------------------------

Would also be great to add test to make sure that we don't regress on this next 
time. 

Along the lines of 
{code:java}
split = new Split()
bytes = write(split)
clone = read(bytes)
assertEquals(split, clone){code}

> HoodieRealtimeFileSplit losing info when serialized/deserialized

> But it didn't corresponding modify the {{{}readFields{}}}, {{write}} routines 
> that Hive is using to ser/de splits, meaning that essentially this info is 
> lost upon passing the data b/w executors.
