Till Rohrmann created FLINK-3088: ------------------------------------ Summary: WritableSerializer cannot copy writable object Key: FLINK-3088 URL: https://issues.apache.org/jira/browse/FLINK-3088 Project: Flink Issue Type: Bug Components: Core Affects Versions: 1.0.0, 0.10.1 Reporter: Till Rohrmann Assignee: Till Rohrmann
The {{WritableSerializer}}, {{ValueSerializer}}, {{AvroSerializer}}, {{WritableComparator}} and {{ValueComparator}} use plain {{Kryo}} instances to copy the objects. In cases where {{Kryo}} fails to copy the object, e.g. missing no-arg constructor, the serializer and comparator instances fail even though the objects are serializable. As a fallback strategy I propose to copy the objects by serializing and deserializing them. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
