> The DN process uses around 20 GB of RSS after startup and does not release
> the memory even though rocksdb is closed for every container.
> The capacity used by AbstractDatanodeStore is default capacity * MB. Since
> default capacity is 64MB therefore block cache is passed a capacity of 64TB.
> After the fix the DN memory usage drops to ~3GB.
