carp84 opened a new pull request #9235: [FLINK-13228][tests][filesystems] 
Harden HadoopRecoverableWriterTest
URL: https://github.com/apache/flink/pull/9235
 
 
   ## What is the purpose of the change
   Currently test cases will fail when trying to close the output stream if all 
data written but `ClosedByInterruptException` occurs at the ending phase. This 
PR proposes to close the stream silently if the test case logic passed properly.
   
   ## Brief change log
   Close the output stream silently in `HadoopRecoverableWriterTest` if the 
test case logic passed properly.
   
   
   ## Verifying this change
   This change is on the test cases and verified by sanity test through 
modifying hadoop source code to simulate the rarely happening situation that 
triggers the issue.
