Kihwal Lee commented on HDFS-10569:
-----------------------------------

It looks like {{index2BlockId()}} was used to get the right index before the change.
[~daryn], please have a look.

> 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.
