TestBPOfferService#testMissBlocksWhenReregister fails on trunk
[ https://issues.apache.org/jira/browse/HDFS-15674?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17233582#comment-17233582 ]
Masatake Iwasaki commented on HDFS-15674:
-----------------------------------------
The test intermittently fails if count of reported block in IBRs does not reached to expected value(4000).
{noformat}
[ERROR] Failures:
[ERROR] TestBPOfferService.testMissBlocksWhenReregister:341 Timed out wait for IBR counts FBRCount = 2441, IBRCount = 3999; expected = 4000. Exception: Timed out waiting for condition. Thread diagnostics:
Timestamp: 2020-11-16 12:45:57,425
{noformat}
This waiting condition does not make sense because pending IBRs are possible to be deleted by {{clearIBRs()}} in {{BPServiceActor#reRegister}}. It is ok because succeeding full block report covers them based on the discussion of HDFS-15113.
The tests should check that all blocks are reported rather than counting number of reported blocks in FBR/IBR independently.
I submitted [PR #2467|https://github.com/apache/hadoop/pull/2467] for this.
