Tsz Wo (Nicholas), SZE updated HDFS-4188:

    Attachment: h4188_20121114.patch

h4188_20121114.patch: fixes a bug for ReadOnlyList.Util.binarySearch(..).  It cannot use Collections.binarySearch(..)
since it may call listIterator() which is not supported in ReadOnlyList.

> The Snapshot class currently has two compareTo methods. The one for comparing IDs is
not implementing the Comparable interface since Java does not allow implementing the same
interface twice with different generic types.  It is better to remove one of the compareTo
methods for avoiding confusion.
