重点搜索了一下最开始的Error:KeeperErrorCode = NoNode for /hbase/root-region-server

找到一篇：http://mail-archives.apache.org/mod_mbox/hbase-user/201106.mbox/%3CBANLkTimCgHr-1MDtdo3NETZMrQXkBJy=dA@mail.gmail.com%3E

里面提到可能因为localhost和机器名不一样，且映射到不丗IP（我的是localhost->127.0.0.1,ubuntu->127.0.1.1），将两者映射至相同IP（127.0.0.1）就可以了，试了一下，在改动后可以在SHELL里建表了，算是成功启动了
