Hudson commented on HDFS-2106:
------------------------------
Integrated in Hadoop-Hdfs-trunk #710 (See
[https://builds.apache.org/job/Hadoop-Hdfs-trunk/710/])
Fix CHANGES.txt (HDFS-2106 should be HDFS-2107) and add NumberReplicas.java.
HDFS-2106. Move block management code from o.a.h.h.s.namenode to a new package
o.a.h.h.s.blockmanagement.
