Huaxiang Sun commented on HBASE-27125:
--------------------------------------
This was released in 2.4.13, due to fix scope error, it was marked as 2.4.14 so
it did not show up in 2.4.13 release notes. Fix it now.
> The batch size of cleaning expired mob files should have an upper bound

> Currently the cleaning logic for expired mob files is adding all the
> deletable files in one directory to a list in memory and then archiving all
> the files in the list. But when there are millions of files need to delete,
> the list will be huge and make great heap memory pressure to the master.
