> Hive AvroSerDe does not support circular references in Schema
> -------------------------------------------------------------
>
> Key: HIVE-7653
> URL: https://issues.apache.org/jira/browse/HIVE-7653
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.13.1
> Reporter: Sachin Goyal
> Assignee: Sachin Goyal
> Attachments: HIVE-7653.1.patch, HIVE-7653.2.patch, HIVE-7653.3.patch,

>
> Avro allows nullable circular references but Hive AvroSerDe does not.
> Example of circular references (passing in Avro but failing in AvroSerDe):
> {code}
> class AvroCycleParent {
> AvroCycleChild child;
> public AvroCycleChild getChild () {return child;}
> public void setChild (AvroCycleChild child) {this.child = child;}
> }
> class AvroCycleChild {
> AvroCycleParent parent;
> public AvroCycleParent getParent () {return parent;}
> public void setParent (AvroCycleParent parent) {this.parent = parent;}
> }
> {code}
> Due to this discrepancy, Hive is unable to read Avro records having
> circular-references. For some third-party code with such references, it
> becomes very hard to directly serialize it with Avro and use in Hive.
> I have a patch for this with a unit-test and I will submit it shortly.
