Subject regarding to HBase Rest service
Date Tue, 10 Nov 2009 21:01:46 GMT
Hi,

I noticed that there is a HBase Rest service which provides nice features
that directly talks to HBase.
Does it run MR under the hood?
What is the difference between using normal MR to fetch the data and using
REST to fetch the data?
Will it introduce resource contention?

I am concerned about the performance if we launch such service on a system
that already under a heavy load.

thanks
zhenyu
