FAQ
Hello,

I set up HADOOP_MASTER property to point to root of my namenode
ie. /usr/local/hadoop-0.20.2

when I start hadoop cluster with start-all.sh script everything in
/usr/local/hadoop-0.20.2 vanished :-)

after that I set up new installation to
/usr/local/hadoop-0.20.2-master
and to
/usr/local/hadoop-0.20.2
set HADOOP_MASTER=/usr/local/hadoop-0.20.2-master
and run start-all.sh from
/usr/local/hadoop-0.20.2

this time all changes in /usr/local/hadoop-0.20.2-master were copied on all
nodes and my namenode config hasn't vanished.

Do I do it correctly or there is a simpler way?

Regards,
Vitaliy S
