For example, If I have a table that has two region=EF=BC=88region1,region2=EF= =BC=89, and I sent a Scan() to this Table. This Scan will be send to region1 first and until region1 returned, region2 can get this Scan? So If There are some methods than I can control the sequence? some time I need region2 to search fist, because it has my own index. Then It will give an suggest to other region about where to search.. I am using zookeeper to do this, But I found that My scan will be blocked for my lock on region1, and region2 who has the suggest, even't can't receive this scan. Anyone have suggest? Thanks very much --001a113f458cdd59ac0562d27565--
