Hudson commented on HDFS-3394:
------------------------------
Integrated in Hadoop-Hdfs-trunk #1053 (See
[https://builds.apache.org/job/Hadoop-Hdfs-trunk/1053/])
HDFS-3394. Do not use generic in INodeFile.getLastBlock(): the run-time
ClassCastException check is useless since generic type information is only
available in compile-time. (Revision 1341141)
Result = SUCCESS
