   Hi @pjfanning - Would you ignore the findbugs error? 
   
   >  A known null value is checked to see if it is an instance of org.apache.avro.util.Utf8 in org.apache.hadoop.mapreduce.jobhistory.JobSubmitted.customDecode(ResolvingDecoder) At JobSubmitted.java:checked to see if it is an instance of org.apache.avro.util.Utf8 in org.apache.hadoop.mapreduce.jobhistory.JobSubmitted.customDecode(ResolvingDecoder) At JobSubmitted.java:[line 1238]
   
   The class is generated by Avro and the generated source code is as follows. I think it is a bug in Avro side and we can simply ignore.
   ```
                 java.lang.CharSequence k0 = null;
                 k0 = in.readString(k0 instanceof Utf8 ? (Utf8)k0 : null);
                 java.lang.CharSequence v0 = null;
                 v0 = in.readString(v0 instanceof Utf8 ? (Utf8)v0 : null);
   ```
   
   Sorry for the late response.
