dhruba borthakur commented on HADOOP-3187:
------------------------------------------
The code to load an fsimage form disk to memory should try to avoid object
allocation if possible, this speeds up namenode restart times.
FSEditLog.readInt() allocates an IntWritbale every time it is invoked. Is this
method being used at fsimage loading time?
