I am working on a project and I want to add things to my code incrementally. When something works, I want to be able to take the entire hbase database, copy it somewhere else, and continue my work. If I messed up, I want to be able to go back to that "checkpoint". I am using HDFS with everything one one server. Is it just a matter of shutting down the hbase and hadoop servers, and then copying the "dfs" and "mapred" folders somewhere else? And then moving them back into place if I need to revert to that state. Or are there other files that need to be copied too? Thanks - Marc --=-G9N1LUtI8yI+TfdYjC0x--
