-----------------------------------
Summary: Remove clearBuffers from the public interfaces of
RecordWriter
Key: FLINK-19320
URL: https://issues.apache.org/jira/browse/FLINK-19320
Project: Flink
Issue Type: Sub-task
Components: Runtime / Task
Reporter: Yingjie Cao
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.
