Hi,
I wanna start using Hadoop. I have Hadoop clusters set up by someone
and I have to try my hands on it. How do I get going with running any
kind of task. Any suggestions ?
Also before running any task what configuration should I make sure are
setup properly. I have not installed it myself so not sure if it is
configured properly for any task. Any suggestions would be
appreciated. Thanks

First check whether hadoop processes (namenode, secondarynamenode,
jobtracker and tasktracker) are running in your clusters or not. Use "ps
-ef" for it. If they are running then you can try any example inside
hadoop tarball or just try to copy data from your local filesystem to
hdfs and back. If the processes are not running than u need to check the
hadoop conf files and your java environment. There are lot of good
tutorials on internet to start with configuration.
Thanks..
