Prasanth Jayachandran commented on HIVE-16671:
----------------------------------------------
{code}
if (ix == 3) break; // Done, we have 3 bytes.
{code}
After this why are we moving on to next DiskRangeList? DiskRangeList will not
be 1 or 2 byte long right? If we can't read complete header in current
DiskRangeList, worst case it will be in next contiguous DiskRangeList. Am I
missing something here?
Will be good to make it a separate method with tests (fake InStreams) if
possible.
