Hi David,
Looks like you're just mis-using the Range here.
If you create a range that is ["row0", "row0"] as you denote below, that
will only include Keys that have a rowId of "row0" with an empty colfam,
colqual, etc. Since you want to use the WholeRowIterator, I can assume
you want all columns in "row0". As such, ["row0", "row0\0") would be the
best range to fetch all of the columns in that single row.

Hi all,
I'm working with the Python Thrift API for the Accumulo proxy service,
and I have a bit of odd behavior happening. I'm using Accumulo 1.5
(the standard one from the Accumulo website).
Whenever I use the WholeRowIterator with a Scanner, I cannot configure
the Range for that Scanner to correctly return the start row for the
Range. E.g. for the Range('row0',true,'row0',true) [to pull a singe
row], it returns zero entries. For Range('row0',true,'row1\0',true),
it returns only "row1".
From the WholeRowIterator documentation, this behavior implies that
the startInclusive bit was set to False, which it clearly wasn't.
I've been able to hack around this issue by setting the start key to
Key(row=(row[:-1]+chr(ord(row[-1])-1))+'\0', inclusive=False)
but I'd really rather understand the correct way of using a Range
object in conjunction with a WholeRowIterator.
Thanks much,
David
