Hi Gandham, I think you can use files on local filesystem if you import the right package in you program. But it doesn't make sense in an distributed environment. So, it is better to load the file into HDFS and use the corresponding IO api to access the files. The example at http://wiki.apache.org/hadoop/HadoopDfsReadWriteExample maybe helpful.

I am trying yo use Hadoop streaming utility. In map reduce program I want to use the files in Local file System. Should I need to copy them into HDFS, if I want to use them? or is there any way that I can access them from local file system itself? If I have to copy into HDFS and use, how can I use or how can I specify in my program such that, my program will access the file in HDFS? And if I can use directly from local file system, how can I use? Can any one help me please. Thank you so much. -- Best Regards, Gandham Santhosh ___________________________________________________________ 好玩贺卡等你发，邮箱贺卡全新上线！ http://card.mail.cn.yahoo.com/
