Description

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

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

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

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

Command used for checking the filehandlers

lsof -p {hive_process_id} > runjarlsof.txt
