Subject Sizing help
Date Fri, 21 Oct 2011 21:40:14 GMT
I am a newbie to Hadoop and trying to understand how to Size a Hadoop
cluster.   

 

What are factors I should consider deciding the number of datanodes ?

Datanode configuration ?  CPU, Memory

Amount of memory required for namenode ? 

 

My client is looking at 1 PB of  usable data and will be running analytics
on TB size files using mapreduce.

 

 

Thanks

... Steve
