Sergey Shelukhin commented on HBASE-10196:
------------------------------------------

As far as I understand null means there's no merge.
+1

should Hbck clean up if Janitor didn't as JM says?

> HBCK will report an error now after the online merge,
> because the files of merging regions still remain on HDFS which will be cleaned by CatalogJanitor
later.
> ERROR: Region { meta => null, hdfs =>
> hdfs://hbasetest1:9000/hbase/data/default/dns/c6569a72cc3c2750d14976ab85f02315,
