-----------------------------------
Summary: SparkSQL Avro serialization doesn't handle enums correctly
Key: HBASE-16247
URL: https://issues.apache.org/jira/browse/HBASE-16247
Project: HBase
Issue Type: Bug
Components: spark
Affects Versions: 2.0.0
Reporter: Sean Busbey
Priority: Critical
Fix For: 2.0.0
Avro's generic api expects GenericEnumSymbol as the runtime type for instances
of fields that are of Avro type ENUM. The Avro 1.7 libraries are lax in some
cases for handling this, but the 1.8 libraries are strict. We should
proactively fix our serialization.
(the lax serialization in 1.7 fails for some nested use in unions, see AVRO-997
for details)
