Using Avro for serializing data to byte[] and deserializing data. https://cwiki.apache.org/confluence/display/AVRO/FAQ#FAQ-HowcanIserializedirectlyto/fromabytearray? shows sample usage.

SpecificDatumReader<User> reader = new SpecificDatumReader<User>(User.getClassSchema());

The above line is causing the following error

IllegalAccessError: tried to access method org.apache.avro.specific.SpecificData.<init>() from class com.abc.schema.generated.User

Any pointers to what might be going wrong here? No errors seen at compile time.

This is likely due to you having an older version of Avro in your classpath. To check, run your program with the -verbose:class parameter and look for instance of SpecificData in the output. Example:

 java -verbose:class -jar your_jar.jar

Changing the class loading from parent-first to child-first fixed this for me
