Jean-Marc Spaggiari commented on HBASE-7930:
--------------------------------------------
First thing, thanks for looking at it!
bq. For the test, can we use the utility assertErrors() and assertNoErrors() in
TestHBaseFsck? By this way, we will be sure the list of expected errors.
Unfortunatly we can't. asserErrors() verifies that ALL the errors you are
giving it are there, and only those errors. However here, there is some other
errors triggered because of the entries removed. I used asserTrue to focus on
the specific ERROR_CODE.EMPTY_META_CELL and not be "polluted" by the other
errors. I can still build the full list of errors triggered if required, and
user assertErrors, but that will also validate some other errors which are not
related to this specific test case.
bq. Should we also put this fix in OfflineMetaRepair?
I don't think we need. OfflineMetaRepair will call rebuildMeta which will call
sidelineOldMeta and createNewMeta. That will backup the meta and create a
proper one, which will not have any empty REGIONINFO_QUALIFIER.
> hbck should provide an option to fix .META. rows with empty
