I found that the performance of Coprocessor is impacted much by the distribution of the regions. I am kind of interested in going deep into this problem and see if I can do something. I only searched out the discussion in the following link. http://search-hadoop.com/m/Vjhgj1lqw7Y1/hbase+distribution+region&subj=3Ddi= stribution+of+regions+to+servers I am wondering if there is any further discussion or any on-going work? Can someone point it to me if there is? Thanks in advance. Best Wishes Dan Han=
