--------------------------------------
Hi [~jingcheng.du], I think the patch looks good. I have one comment. With the
patch, ExpiredMobFileCleanerChore now does not need to acquire a read lock
before removing expired files. While PartitionedMobCompactor is compacting
files, ExpiredMobFileCleanerChore could come in and remove files. This may
cause FileNotFoundException in PartitionedMobCompactor and it is not handled
(compaction will fail). Maybe it needs to handle this exception and do not
abort the compaction? Thanks.
