Congxian Qiu commented on FLINK-11428:
--------------------------------------
After running a couple times of
{{BufferFileWriterFileSegmentReaderTest#testWriteRead}} locally, I find the
direct reason is
[writer.deleteChannel()|[https://github.com/apache/flink/blob/46326ab9181acec53d1e9e7ec8f4a26c672fec31/flink-runtime/src/test/java/org/apache/flink/runtime/io/disk/iomanager/BufferFileWriterFileSegmentReaderTest.java#L91]],
and
{{}}[writer.close()|https://github.com/apache/flink/blob/46326ab9181acec53d1e9e7ec8f4a26c672fec31/flink-runtime/src/test/java/org/apache/flink/runtime/io/disk/iomanager/BufferFileWriterFileSegmentReaderTest.java#L120]
has not been called
[writer.close()|https://github.com/apache/flink/blob/46326ab9181acec53d1e9e7ec8f4a26c672fec31/flink-runtime/src/test/java/org/apache/flink/runtime/io/disk/iomanager/BufferFileWriterFileSegmentReaderTest.java#L120]
before for some reason. Did this just need to catch this situation(do some
check in {{tearDownWriterAndReader}}) or to do more things?
