我是HBase的新手，我正在阅读“Hadoop-The Definitve Guide”一书。 我已经在我的本地系统上启动了所有应用程序，这意味着应该没有网络开销。但是，当我运行简单命令在基础中创建一个表时，大约需要9秒钟。
以下是我用来启动hbase和create table的过程：
./start-hbase.sh
./hbase shell
create 'test' , 'data'
这是控制台日志，显示大约需要8.3秒：
hbase(main):002:0> create 'test' , 'data'
0 row(s) in 8.3310 seconds
=> Hbase::Table - test
虽然基础日志中没有错误或异常。作为参考，这是我的hbase-KV-master-KV.local.log文件：

任何建议，可能是什么问题？为什么需要这么长时间？
