Date Thu, 30 Oct 2014 02:53:34 GMT

Lei (Eddy) Xu updated HDFS-7035:
--------------------------------
    Attachment: HDFS-7035.014.patch

[~cmccabe] I made changes based on your comments. Thanks!

bq. this isn't needed because VolumeBuilder is in the same Java package as Storage.

This function is {{BlockPoolSliceStorage#addStorageDir}}, which is called by {{DataStorage#VolumeBuilder}}.
I could not use {{protected}} or project visibility here.

> It refactors {{DataStorage}} and {{BlockPoolSliceStorage}} to reduce the duplicate code
and supports atomic adding volume operations. Also it parallels loading data volume operation:
each thread loads one volume.
