> This issue can be reproduced by below steps:
> * make a hfile contains two rows '000' and '001';
> {code:java}
> D:\bin>hbase hfile -p -f /hbase/data/default/test2/df76e4acab5398e70be332f6807ec3ba/f1/fda213c556d540a58d29d6bd85931dcd
> K: 000/f1:a/1601282789548/Put/vlen=4/seqid=4 V: aaaa
> K: 001/f1:a/1601282792779/Put/vlen=4/seqid=5 V: aaaa
> Scanned kv count -> 2{code}
> * '001' can be seeked to;
> {code:java}
> D:\bin>hbase hfile -e -w 001 -f /hbase/data/default/test2/df76e4acab5398e70be332f6807ec3ba/f1/fda213c556d540a58d29d6bd85931dcd
> K: 001/f1:a/1601282792779/Put/vlen=4/seqid=5
> Scanned kv count -> 1{code}
> * but '000' can't be seeked to;
> {code:java}
> D:\bin>hbase hfile -e -w 000 -f /hbase/data/default/test2/df76e4acab5398e70be332f6807ec3ba/f1/fda213c556d540a58d29d6bd85931dcd
> Scanned kv count -> 0{code}
> In HFilePrettyPrinter we use "scanner.seekTo(PrivateCellUtil.createFirstOnRow(this.row))" to seek to row.But this method will retrurn -1 when the row is the first row of hfile.
