Hey hbasers,
I'm working on pushing predicates down from Hive, and starting with a very
basic case (equality on a simple key). This ends up looking like a get, but
for now it still uses TableInputFormatBase since later we'll be extending it to
range scans as well.
After converting the key to byte [] startRow, I do the following, since stopRow
is exclusive rather than inclusive:
byte [] stopRow = new byte[startRow.length + 1];
System.arraycopy(startRow, 0, stopRow, 0, startRow.length);
scan.setStartRow(startRow);
scan.setStopRow(stopRow);
I just wanted to confirm
(a) Is this the correct way to create a stopRow for a point lookup (appending a
single zero byte to make the successor lexical value)?
(b) Do I also need a WhileMatchFilter, or is setStartRow+setStopRow guaranteed
to do all the filtering directly?
Thanks,
JVS
