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.
