comment How much power supply do I need for my server, and could a shortage be causing my odd crashing?
Understandable.. I added more details on my particular hardware. You make a good point on using a power meter. Can you think of any other measures I can do now for determining if power is maxing out vs. some other system issue (e.g. system logs, etc)?

comment Hadoop: Blacklisted tasktracker
I just noticed that there are two separate settings for defining hosts (dfs.hosts and mapred.hosts). I never figured out how to restore blacklisted tasktrackers for a job, but I was trying "dfs.hosts", which in hindsight, doesn't make sense (I should have tried mapred.hosts and then the restart). If Roberto or David have insight, please share :)

comment Hadoop: Blacklisted tasktracker
Any idea if this should work if I put the setting in hdfds-site.xml while the job is running? I tried this, refreshed, then restarted task tracker on slave, but it is still not doing work, and shows in web interface as blocked.

comment Are the Hadoop {start|stop}-all.sh scripts typically used w/ cloudera 3 clusters, and if so, how?
I didn't see anything about starting/stopping the slave nodes from one server, which is what I'm looking for. Currently I can already use the etc/init.d scripts to start/stop locally. Let me know if I missed something please

Puppet's new to me, but it looks like a promising solution. If you got any favorite how-to's (outside of their documentation) or ways you've used, please let me know. Thanks!
