------------------------------------------
HDFS-2938 does this issue not solving for you? (for large delete)
> is there any operation that has the potential to severely starve other
> clients?
In general due to fsn lock, if we do big operations under lock, yes it starve
other clients. But in the existing apis, I am not sure any one making such big
ops. did you list some?
