Keith Turner commented on ACCUMULO-4586:
----------------------------------------
I was just looking at the javadoc for RowIterator again. It has two
constructors. One constructor has the following javadoc.
{noformat}
public RowIterator(Iterator<Map.Entry<Key,Value>> iterator)
Create an iterator from an (ordered) sequence of KeyValue pairs.
{noformat}
So maybe it would make sense to add the sanity check. Earlier I only looked at
the class javadoc, which says nothing about order. The other constructor has
the following javadoc, which does not mention order.
{noformat}
public RowIterator(Iterable<Map.Entry<Key,Value>> iterable)
Create an iterator from an Iterable.
{noformat}
> Make rowiterator fail when unsorted data is observed

> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.6.6, 1.7.1, 1.8.0
> Reporter: Keith Turner
> Fix For: 2.0.0

>
> A batchscanner was used as a row iterator data source. The rowiterator
> expects data in sorted order and the batch scanner does not supply data in
> sorted order. The row iterator should have a sanity check to ensure source
> data is in sorted order.
