bvaradar commented on issue #741: java.lang.NoClassDefFoundError: com/uber/hoodie/exception/HoodieException URL: https://github.com/apache/incubator-hudi/issues/741#issuecomment-503739001 @amaranathv : The invalid dataset is not an error message per se. Apache Hudi implements optimistic concurrency for guaranteeing Key uniqueness even in the face of Spark Stage level retries. This message merely indicates that some Stage level retry happened during ingestion and Hudi identified some duplicate files that got created. Hudi will remove this file before committing the data. So, this message is innocuous. Are you noticing any record loss ?
