URL: https://github.com/apache/hadoop/pull/4366#issuecomment-1143182980
In the original PipelineRecovery process, if the pipeline recovery failed,
the block GS maybe inconsistency. So during Pipeline Recovery, GS inconsistency
is expected.
[HDFS-16534](https://issues.apache.org/jira/browse/HDFS-16534) has a bug in
handling inconsistent GS, and caused **All datanodes XXX are bad.
Aborting...**
