Can't start the namenode

[Mark Kerzner <ma...@gmail.com>]

Hi,

when I am trying to start a namenode in pseudo-mode

sudo /etc/init.d/hadoop-0.20-namenode start


I get a permission error


java.io.FileNotFoundException:
/usr/lib/hadoop-0.20/logs/hadoop-hadoop-namenode-myservername.log
(Permission denied)


However, it does create another log file in the same directory


ls /usr/lib/hadoop-0.20/logs

hadoop-hadoop-namenode-myservername.out


I am using CDH3, what am I doing wrong?


Thank you,

Mark

I kind of found the problem. If I open the logs directory, I see that this
log file is created by hdfs

-rw-r--r-- 1 hdfs hdfs 1399 Jul  6 21:48
hadoop-hadoop-namenode-myservername.log

whereas the rest of the logs are created by root, and they have no problem
doing this.

I can adjust permissions on the logs directory, but I would expect this
automatics.
