Hi,
When I am running the following command in Mandriva Linux
hadoop namenode -format
I am getting the following error:
10/10/09 22:32:07 INFO namenode.NameNode: STARTUP_MSG:
/
STARTUP_MSG: Starting NameNode
STARTUP_MSG: host = java.
Hi,
I am also getting the following error. Please tell me whether this error is
related to the previous error which I asked an hour before or this is a
separate error...
[u...@cs-sy-249 hadoop]$ bin/hadoop dfs -copyFromLocal

I suggest you change the hadoop.tmp.dir value in hadoop-site.xml
(0.19.x) and reformat, restart it. Also double check the host machine
in fs.default.name and mapred.job.tracker is reachable or not.

Hi Shi,
I am a beginner in Hadoop. I have given the following value in core-site.xml
hadoop.tmp.dir
/users/user/hadoop-datastore/hadoop
fs.default.name
hdfs://localhost:54310
How will we check whether the host machine is reachable or not?
Also, in mapred-site.xml, I have given
mapred.job.trac
Hi. Were you trying hadoop on your own computer or on a cluster? My
guess you were trying on your own computer. I once observed the same
problem on my laptop when I switched from wireless to fixed line
connection, since the IP address was changed but for some reason the
configuration was not up
Hi,
Thanks for your reply..
In browser,
http://localhost:50030/jobtracker.jsp is opening fine
but
http://localhost:50060/ is not.
Since jobtracker is running, so I'm assuming localhost is reachable.. am I
wrong??

Check you log, especially the hadoop-**-tasktracker-TEMP.log. What does
it say?

I'd worry more
Check your etc/hosts file. I usually resolve this issue by fixing some
weirdness or misconfiguration in that file.

That said, I've seen problems if your resolv.conf is a mess and the
machine can't even work out its own hostname:
