Subject Re: [VOTE] Release Apache Flink 0.10.0 (release-0.10.0-rc0)
Date Thu, 22 Oct 2015 12:53:00 GMT
I found another issue (FLINK-2894
<https://issues.apache.org/jira/browse/FLINK-2894>) while helping the
mahout guys with the flink bindings for Samsara. Currently we don't allow
to register default serializer for Kryo. This means it is not possible to
specify a serializer for a base class and all its subclasses. In order to
push the flink integration with Samsara, I would like to include a fix for
it in 0.10.
