Hadoop Log4j ?
It seems I'm having a lot of trouble trying to configure hadoop on one
machine.
I've followed the wiki tutorial and I've configured every thing on 1
machine. I tried to start hadoop using start-all.sh and it works. I've the
following output:
starting namenode, logging to /data/sengine/search/logs/hadoop-
nutch-namenode-node-n1.out
localhost: starting datanode, logging to /data/sengine/search/logs/hadoop-
nutch-datanode-node-n1.out
cat: /data/sengine/search/bin/../conf/masters: No such file or directory
starting jobtracker, logging to /data/sengine/search/logs/hadoop-
nutch-jobtracker-node-n1.out
localhost: starting tasktracker, logging to
/data/sengine/search/logs/hadoop-nutch-tasktracker-node-n1.out
However do you have any idea why i've an error about a file name masters ?
In the task manager i can see 3 process up and running:
1=>> /usr/local/java/bin/java -Xmx1000m -

I tried to start to crawl a website and I had the following error:

Any idea why I've this error ?
I confirm that my log4j properties file is well defined and is located in
conf folder.
Thanks in advance for your help

RE: Hadoop Log4j ?
Posted by Dhruba Borthakur <dh...@yahoo-inc.com>.
The filename "masters" lists the machines on which you might want to run the
Secondary Namenode. The Secondary Namenode periodically merges the HDFS
transaction log with the file system image. If you do not run a Secondary
Namenode, then the NameNode does this functionality when it starts up.
Hope this helps,
dhruba

Hadoop Log4j ?
Posted by Emmanuel JOKE <jo...@gmail.com>.
It seems I'm having a lot of trouble trying to configure hadoop on one
machine.
I've followed the wiki tutorial and I've configured every thing on 1
machine. I tried to start hadoop using start-all.sh and it works. I've the
following output:
starting namenode, logging to /data/sengine/search/logs/hadoop-
nutch-namenode-node-n1.out
localhost: starting datanode, logging to /data/sengine/search/logs/hadoop-
nutch-datanode-node-n1.out
cat: /data/sengine/search/bin/../conf/masters: No such file or directory
starting jobtracker, logging to /data/sengine/search/logs/hadoop-
nutch-jobtracker-node-n1.out
localhost: starting tasktracker, logging to
/data/sengine/search/logs/hadoop- nutch-tasktracker-node-n1.out
However do you have any idea why i've an error about a file name masters ?
In the task manager i can see 3 process up and running:
1=>> /usr/local/java/bin/java -Xmx1000m -

Good point.
I'm having the same problem and still haven't figured out how to fix this.
