Question

我一直在关注此页面上给出的HBase安装说明： https://hbase.apache.org/book.html#quickstart

我正在使用HBase 1.1.3版（稳定版）并已在独立模式下配置。我已经安装了OpenJDK 7

当我尝试启动hbase时，它在几秒钟后崩溃，我收到以下错误：

有谁能告诉我这个错误的原因？如果您需要更多信息，请与我们联系。

导致此问题的异常是NoClassDefFoundError，这通常意味着您遗漏了类路径中的内容。在这种情况下，您遗漏了来自org.apache.hadoop.hbase.util.Bytes的{{1}}。但是，如果缺少一个，也可能有其他人。这可能意味着您以错误的方式启动HBase。您是否尝试过包含的启动脚本？
