Subject [jira] [Created] (HBASE-16247) SparkSQL Avro serialization doesn't handle enums correctly
Date Tue, 19 Jul 2016 15:17:20 GMT
Sean Busbey created HBASE-16247:
-----------------------------------

             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)
