Mike Drob commented on HBASE-18987:
-----------------------------------
{code}
+ String nameStr = Bytes.toString(name);
{code}
This one is unused too, I should have caught it the first time.
+1 assuming tests pass otherwise
> Raise value of HConstants#MAX_ROW_LENGTH

> Short.MAX_VALUE hasn't been a problem for a long time but one of our
> customers ran into an edgy case when the midKey used for the split point was
> very close to Short.MAX_VALUE. When the split is submitted, we attempt to
> create the new two daughter regions and we name those regions via
> {{HRegionInfo.createRegionName()}} in order to be added to META.
> Unfortunately, since {{HRegionInfo.createRegionName()}} uses midKey as the
> startKey {{Put}} will fail since the row key length will now fail checkRow
> and thus causing the split to fail.
> I tried a couple of alternatives to address this problem, e.g. truncating the
> startKey. But the number of changes in the code doesn't justify for this edge
> condition. Since we already use {{Integer.MAX_VALUE - 1}} for
> {{HConstants#MAXIMUM_VALUE_LENGTH}} it should be ok to use the same limit for
> the maximum row key.
