---------------------------------------

             Summary: HFilePrettyPrinter can't seek to the row which is the first row of a hfile
                 Key: HBASE-25115
                 URL: https://issues.apache.org/jira/browse/HBASE-25115
             Project: HBase
          Issue Type: Bug
          Components: HFile, tooling
    Affects Versions: 2.2.6
            Reporter: Chaoqiang Zhong


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.
