---------------------------------
Summary: ClassCastException when calling compareTo method on
AvroBagWrapper
Key: PIG-3609
URL: https://issues.apache.org/jira/browse/PIG-3609
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.12.0
Reporter: Richard Ding
Priority: Minor
One got the following exception when calling compareTo method on AvroBagWrapper
with an AvroBagWrapper object:
{code}
java.lang.ClassCastException: org.apache.pig.impl.util.avro.AvroBagWrapper
incompatible with java.util.Collection
at org.apache.avro.generic.GenericData.compare(GenericData.java:786)
at org.apache.avro.generic.GenericData.compare(GenericData.java:760)
at
org.apache.pig.impl.util.avro.AvroBagWrapper.compareTo(AvroBagWrapper.java:78)
{code}
Looking at the code, it compares objects with different types:
{code}
return GenericData.get().compare(theArray, o, theArray.getSchema());
{code}
