> Key: HDFS-13928
> URL: https://issues.apache.org/jira/browse/HDFS-13928
> Project: Hadoop HDFS
> Issue Type: Improvement
> Affects Versions: 3.1.1
> Reporter: Yiqun Lin
> Priority: Major
>
> We find some corner cases for log roll when doing jounalnode migration in our cluster. We use a online way for the migration. And there will cause some corner cases:
> * Multiple in-progress edits_inprogress* files exists in edits dir, if log roll is updated correctly. In this case, we can divide this into two cases:
> 1.With redundant in-progress file with higher txid than current in-progress file
> 2.With redundant in-progress file with lower txid than current in-progress file
> * In a HA mode, SBN is down, what's the behavior of log roll will become?
> We can complete the log roll UTs for above cases.
