Subject [jira] [Commented] (HBASE-7928) Scanning .META. with startRow and/or stopRow is not giving proper results
Date Mon, 25 Feb 2013 16:24:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7928?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13585971#comment-13585971
] 

Jean-Marc Spaggiari commented on HBASE-7928:
--------------------------------------------

It seems it's only impacting .META. (and maybe a bit -ROOT- too...)

{code}
    try {
      HTable metaTable = new HTable(config, Bytes.toBytes("-ROOT-"));
      Scan scan = new Scan();
      scan.setStartRow(new byte[]{0});
      //scan.setStopRow(new byte[]{127});
      ResultScanner scanner = metaTable.getScanner(scan);
      Result[] results = scanner.next(100);
      while (results.length > 0) {
        for (Result result : results) {
          System.out.println(Bytes.toString(result.getRow()));
        }
        results = scanner.next(100);
      }
      scanner.close();
      metaTable.close();
    } catch (Exception e) {
      e.printStackTrace();
    }
{code}

This is working for for ROOT, but not if I setup the stoprow.

> This code will not return any result even if there is 10 tables with names starting with
"d" to "w", including one table called "entry". If you comment the setStopRow you will get
results, but will still get rows starting with "d" even if setStartRow is set to "e".
> Same code using with a user table is working fine.
> Facing the same issue with the shell.
> scan '.META.' , {STARTROW => 'e', LIMIT => 10} is returning rows starting by "d".
> scan '.META.' , {STARTROW => 'e', STOPROW => 'v', LIMIT => 10} is not returning
anything.
