Eli Collins commented on HDFS-2019:
-----------------------------------
Previously FSdataset#recoverDetachedBlocks just returns if the detach directory
is empty, now it throws an IOException, why is that? Is it always the case that
the detach directory be non-empty?
> Fix all the places where Java method File.list is used with FileUtil.list API
