Seeing as there is no search function on the archives, I'm relegated
to asking a possibly redundant question or four:
I have, as a sample setup:
idx1-tracker JobTracker
idx2-namenode NameNode
idx3-slave DataTracker
...
idx20-slave DataTracker
Q1: Can I put the same hadoop-site.xml file on all machines or do I need
to configure each machine separately?
Q2: My current setup does not seem to find a primary namenode, but instead
wants to put idx1 and idx2 as secondary namenodes; as a result, I am
not getting anything usable on any of the web addresses (50030, 50050,
50070, 50090).
Q3: Possibly connected to Q1: The current setup seems to go out and start
on all machines (masters/slaves); when I say "bin/start-mapred.sh" on
the JobTracker, I get the answer "jobtracker running...kill it first".
Q4: Do I even *need* a secondary namenode?
IWBN if I did not have to maintain three separate configuration files
(jobtracker/namenode/datatracker).
