ubuntu - HBaseClient : The znode for the -ROOT- region doesn't exist

Question

我按照说明设置 OpenTSDB:http://opentsdb.net/getting-started.html和 http://opentsdb.net/setup-hbase.html .在我使用命令启动 opentsdb 后:

./build/tsdb tsd --port=80 --staticroot=/opt/opentsdb/build/staticroot --cachedir=/tmp/tsd

我收到以下错误:

2013-10-04 22:59:40,577 ERROR [main-EventThread] HBaseClient: The znode for the -ROOT- region doesn't exist!

这是来自 hbase 的日志文件:

我也遇到了这个问题。我通过更改/etc/hosts 文件解决了这个问题。它可能看起来像这样:

127.0.0.1 localhost

127.0.1.1 hostname

将其更改为:

127.0.0.1 localhost

127.0.0.1 hostname
