Change Logs
The precision is incorrect for evolution from float to double and has been fixed for most of spark by #13188. However, there are some edge cases that still need to be fixed.
This pr fixes avro log blocks the evolution is fixed by adding the float -> double conversion into the method that determines if we need to manually convert the record (and the manual conversion already has the float->double conversion correct)
