> StorageInfoDefragmenter floods log when compacting StorageInfo TreeSet. In
> {{StorageInfoDefragmenter#scanAndCompactStorages}}, it prints for all the
> StorageInfo under each DN. If there are 1k nodes in cluster, and each node
> has 10 data dir configured, it will print 10k lines every compact interval
> time (10 mins). The log looks large, we could switch log level from INFO to
> DEBUG in {{StorageInfoDefragmenter#scanAndCompactStorages}}.
