machine-config file

[Benben Xu]

Dear all,

I've spend a whole day to debug my program, just now, I have caught the bug! I want to share with you, maybe it can help.

When you look at your machine-config file, and it shows like this bellow:

gxcissad@node2-OptiPlex-7010:~/GPS/trunk/master-scripts$ hadoop fs -cat /machine-configs/test_machine_config.cfg

-1 localhost 1111

0 localhost 2222

1 localhost 3333

2 localhost 4444

3 localhost 5555

4 localhost 6666

gxcissad@node2-OptiPlex-7010:~/GPS/trunk/master-scripts$ 

Then, you must meet an Exception in the 'main' , called  "

java.util.NoSuchElementException

Exception at com.google.common.base.Splitter$AbstractIterator.next(Splitter.java:469)"

Then, how to solve this????

Just remove the last line in your machine-config file!! there is a blank line !

The machine-config file should looked like this :

gxcissad@node2-OptiPlex-7010:~/GPS/trunk/master-scripts$ hadoop fs -cat /machine-configs/test_machine_config.cfg

-1 localhost 1111

0 localhost 2222

1 localhost 3333

2 localhost 4444

3 localhost 5555

4 localhost 6666

gxcissad@node2-OptiPlex-7010:~/GPS/trunk/master-scripts$
