Subject [jira] Created: (HADOOP-1439) Add endRow parameter to HClient#obtainScanner
Date Tue, 29 May 2007 17:12:15 GMT
Add endRow parameter to HClient#obtainScanner
---------------------------------------------

                 Key: HADOOP-1439
                 URL: https://issues.apache.org/jira/browse/HADOOP-1439
             Project: Hadoop
          Issue Type: Improvement
          Components: contrib/hbase
            Reporter: stack
            Assignee: stack
            Priority: Minor


Currently the HClient#obtainScanner looks like this:

{code}
public synchronized HScannerInterface obtainScanner(Text[] columns, Text startRow) throws
IOException;
{code}

Add an overload that allows specification of endRow:

{code}
public synchronized HScannerInterface obtainScanner(Text[] columns, Text startRow, Text endRow)
throws IOException;
{code}

Use Case: Table contains the whole web.  Client just wants to scan google's pages.  Currently,
client could cut off the scanner as soon as the row key leaves the google domain but cleaner
if {{HScannerInterface#next()}} returns false
