Review Comment:
No need to catch IOException and throw. Just let it throw.
```suggestion
RemoteEditLogManifest remoteEditLogManifest =
journal.getEditLogManifest(1, true);
assertNotNull(remoteEditLogManifest);
assertEquals(1, remoteEditLogManifest.getLogs().size());
RemoteEditLog remoteEditLog = remoteEditLogManifest.getLogs().get(0);
assertTrue(remoteEditLog.isInProgress());
assertEquals(6, remoteEditLog.getStartTxId());

I will let @jojochuang take the lead on this one since he has already been participating in discussion on the Jira; I'm not too sure what the right path forward is here. Taking [the example shared](https://issues.apache.org/jira/browse/HDFS-16645?focusedCommentId=17572129&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17572129), I'm not confident the current diff will fully solve the problem, since you'll still have in-progress gaps:
```
Example:
edits_1000_1005
edits_inprogress_1006
edits_1010_1015
edits_inprogress_1016
```

@xkrogen Thanks for your comment.
do you want to remove the redundant in-progress segment? This diff is only fix the exception "Invalid log manifest".
If we plan to remove the redundant in-progress segment, we can use JournalNodeSyncer asynchronously to fix it, such as copying the finalized segment from other JNs and replace it.
@jojochuang Master, I'm looking forward your ideas, so that we can push this bug forward.
