-----------------------------------

The failed test is passing for me with the patch. HDFS-10572 probably fixed it.
+1 the patch looks good.

> An obvious bug in LongsDecoder.getBlockListAsLongs(), the size of var *longs* 
> is +2 to the size of *values*, but the for-loop accesses *values* using 
> *longs* index. This will cause OutOfIndex.
