Weijie Guo updated FLINK-31626:
-------------------------------
Description: In FLINK-30189, {{HsSubpartitionFileReaderImpl}} will skip the
buffer has been consumed from memory to avoid double-consumption. But these
buffers were not returned to the {{BatchShuffleReadBufferPool}}, resulting in
read buffer leaks. In addition, all loaded buffers should also be recycled
after data view released. (was: In FLINK-30189,
{{HsSubpartitionFileReaderImpl}} will skip the buffer has been consumed from
memory to avoid double-consumption. But these buffers were not returned to the
{{BatchShuffleReadBufferPool}}, resulting in read buffer leaks.)
> HsSubpartitionFileReaderImpl should recycle skipped read buffers.
