Question

所以我已按照Accumulo User Manual中的说明配置并初始化了accumulo。

在conf/accumulo-site.xml中，我将trace.user设置为accumulo_tracer，我还创建了一个具有相同名称的系统用户。此外，我将密码存储在trace.token.property.password属性下的同一文件中。

然而，在./bin/start-all.sh之后，一切都很好，包括accumulo UI。但logs/tracer_localhost.log文件中显示以下错误。

任何可能遗漏某些内容的帮助或指导都会非常有帮助！提前谢谢！

Answer 1

您无需使用该名称创建系统用户。您需要的是创建具有该名称的 Accumulo 用户。您可以在accumulo shell中以（Accumulo）root用户$ACCUMULO_HOME/bin/accumulo shell -u root执行此操作。您还需要向用户授予表创建表的权限。请参阅shell中的help grant以了解如何为该用户设置CREATE_TABLE系统权限。

Answer 2

所以这就解决了我的问题：一个新的 init !!

因此，在 init 阶段，我为 root 用户提供了密码，并且我应该在 conf / accumulo-site中提及相同的密码.XML

<property>
  <name>instance.secret</name>
  <value>your_own_secret_password</value>
  <description>A secret unique to a given instance that all servers must know in order to communicate with one another.
  Change it before initialization. To
  change it later use ./bin/accumulo org.apache.accumulo.server.util.ChangeSecret --old [oldpasswd] --new [newpasswd],
  and then update this file.
  </description>
</property>

之后，一切都像魅力一样。希望有所帮助。发布任何疑问，都很乐意提供帮助。
