Hudson commented on HDFS-3385:
------------------------------
Integrated in Hadoop-Hdfs-trunk #1040 (See
[https://builds.apache.org/job/Hadoop-Hdfs-trunk/1040/])
HDFS-3385. The last block of INodeFileUnderConstruction is not necessarily
a BlockInfoUnderConstruction, so do not cast it in
FSNamesystem.recoverLeaseInternal(..). (Revision 1336976)
Result = FAILURE
