Jagannathrao Mudda updated AVRO-2514:
-------------------------------------
Description:
In certain scenarios when there is a serialization error, avro serializer gives
following error messages that are not actionable without any schema name
and/field name in it.
* java.lang.Double cannot be cast to java.lang.Long
* Not an enum: null
* ClassCastException
* ..
If there is a filed name of specific schema that is causing these serialization
errors, that helps to fix such issues quickly.
*Proposed Changes:*
The "writeWithoutConversion" method of "GenericDatumWriter" class can be
updated to handle "ClassCastException" along with "NullPointerException" to
throw an exception with schema name and field name.
The "writeEnum", "writeField", and "error" method can be enhanced to add field
names so that error message can have the field that is causing the issue.
