1.How does a client get block information from file servers....when client requests one file to process...the request goes to cldb ...then how it is going to find out which block is stored in which container? and if I am running 3 cldbs all are going to have same container info. Can any one please explain me in detail.

2. I am running 3 cldbs it is showing one as master and other 2 as slaves. Is that master is elected by zookeepers and Is it going to be master every time. If a client requests some container or block location, is that request goes to master cldb. how does master and slave cldbs work in MapR.
