Hi,
I am extremely new to Hadoop and have come across a few errors that I'm not
sure how to fix. I am running Hadoop version 0.19.0 from an image through
Elasticfox and S3. I am on windows and use puTTY as my ssh. I am trying to run
a wordcount with 5 slaves. This is what I do so far:
1. boot up the instance through ElasticFox
2. cd /usr/local/hadoop-0.19.0
3. bin/hadoop namenode -format
4. bin/start-all.sh
5. jps --( shows jps, jobtracker, secondarynamenode)
6.bin/stop-all.sh
7. ant examples
8. bin/start-all.sh
9. bin/hadoop jar build/hadoop-0.19.0-examples.jar pi 0 1000000
Then I get this error trace:
Number of Maps = 0 Samples per Map = 1000000

I've searched for some fixes and am not sure if my namenode is in an
inconsistent state or if my ports are incorrectly configured. I cannot access
http://namenode_host:50070/dfshealth.jsp which leads me to believe that this is
a port issue. So I went to my ElasticFox console and ensured that port 22 was
open and that it was an exception to my firewall. However, now I'm stuck.
Please help me. Also, as I am a novice, I would greatly appreicte a detailed
answer so I can understand whats going on!
I greatly appreciate it.
Cheers,
Terri
