hmatu edited a comment on issue #1157: [HUDI-332]Add operation type (insert/upsert/bulkinsert/delete) to HoodieCommitMetadata URL: https://github.com/apache/incubator-hudi/pull/1157#issuecomment-580693541 > > @bvaradar Operation type is stored in the avro objects when archiving, but there are a error here, it throw `ClassCastException: org.apache.avro.generic.GenericData$EnumSymbol cannot be cast to org.apache.hudi.avro.model.WriteOperationType` with `deepCopy` block in 'show archived commit stats' . Can you give any suggestion when you're free. > > @bvaradar I found it cause by [AVRO-1676](https://issues.apache.org/jira/browse/AVRO-1676) and fixed in AVRO-1.8.0. So can i roll back `operationType ` to String type? It may cause other compatibility problem If upgrade avro. Already using `avro-1.8.2` dependency, String type is redundant now, Enum type is enough. https://github.com/apache/incubator-hudi/blob/f27c7a16c6d437efaa83e50a7117b83e5201ac49/pom.xml#L96
