Hi all,

I want to used hadoop system, but I need a overall system info about
hadoop, for example,
system performance, mem used, cpu utilization and so on.  So do anyone have
a system estimate  about hadoop? which tool can do this?

Hey,

It completely depends on your data sizes and processing. You can have
one node cluster to thousands (many more) depending on your needs.
Following link may help you.

Hi Jinyan,

I'd like to introduce you our system Starfish, which can be used to analyze
and estimate the Hadoop performance and memory usage.

With Starfish, you can analyze the performance of your Hadoop job at fine
grained levels, e.g. the time for map processing, spilling, merging,
shuffling, sorting, and reduce processing.  So you can understand which
part is the bottleneck of the performance.

You can also ask "what-if" questions, e.g. "What if I double io.sort.mb ?",
and Starfish will predict the new behaviour of the job, so you can better
understand how these parameters work, and estimate the time for the new job.

In addition, you can simply delegate Starfish to find the optimal
configurations for you to achieve the best performance.

Welcome to join our Google Group to discuss more about Starfish and any
feedback will be appreciated. If you meet any problems, please don't
hesitate to let us know. The Group address is
http://groups.google.com/group/hadoop-starfish.

Thanks,
Jie
