Hudson commented on HDFS-3087: ------------------------------ FAILURE: Integrated in Hadoop-Hdfs-trunk #2090 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/2090/]) HDFS-8025. Addendum fix for HDFS-3087 Decomissioning on NN restart can complete without blocks being replicated. Contributed by Ming Ma.

At this > point the initial block report has not been sent, so the name node thinks the > node has zero blocks and the decomissioning completes very quick, without > replicating the blocks on that node. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
