Resolution: Fixed
> Remove RecordWriter#clearBuffers
> --------------------------------
>
> Key: FLINK-19320
> URL: https://issues.apache.org/jira/browse/FLINK-19320
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Task
> Reporter: Yingjie Cao
> Priority: Major
> Fix For: 1.12.0
>
>
> Currently, RecordWriter#clearBuffers is only used to finish the current
> BufferBuilder and it does not clear buffers any more. Previously, it was used
> to recycle the partially filled buffer in the serializer but currently the
> serializer does not contains any network buffer any more.
> For now, only some tests and DataSet classes use it and all of these usage
> should be replaced by RecordWriter#close which dose the same thing. Besides,
> for FLINK-19297, we do not want to keep this method in the new
> ResultPartitionWriter Interface. So in this ticket, we propose to remove
> clearBuffers from the public interfaces of RecordWriter.
