Date Tue, 11 Jan 2011 10:39:46 GMT
FileHandler leak on partial iteration of the resultset. 
--------------------------------------------------------

                 Key: HIVE-1908
                 URL: https://issues.apache.org/jira/browse/HIVE-1908
             Project: Hive
          Issue Type: Bug
          Components: Server Infrastructure
    Affects Versions: 0.6.0
         Environment: Hadoop 0.20.1, Hive0.6.0 and SUSE Linux Enterprise Server 10 SP2 (i586)
- Kernel 2.6.16.60-0.21-smp (5).
            Reporter: Chinna Rao Lalam



If the "resultset" is not iterated completely ,  one filehandler is leaking

Ex: We need only first row. This case one resource is leaking

{code}

ResultSet resultSet = createStatement.executeQuery("select * from sampletable");

if (resultSet.next())
{
	System.out.println(resultSet.getString(1)+"   "+resultSet.getString(2));
} 

{code}


Command used for checking the filehandlers
{code}
lsof -p {hive_process_id} > runjarlsof.txt
{code}
