Accumulo:用户名或密码无效

Question

因此，我已经配置并初始化了Accumulo用户手册中给出的accumulo。

在conf/accumulo-site.xml中，我将trace.user设置为accumulo_tracer，并创建一个同名的系统用户。此外，我将密码存储在trace.token.property.password属性下的同一个文件中。

然而，在./bin/start-all.sh之后，一切都启动得很好，包括accumulo。但是下面的错误显示在logs/tracer_localhost.log文件中。

任何帮助或指导，我可能会错过一些东西，将是非常有帮助的！提前感谢！

Answer 1

您不需要创建一个具有该名称的系统用户。您需要的是创建一个名为Accumulo的用户。您可以作为( accumulo )根用户$ACCUMULO_HOME/bin/accumulo shell -u root在Accumulo中这样做。您还需要授予用户创建表的权限。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，这就是解决我的问题:一个新鲜的！！

因此，在init阶段，我为根用户提供了一个密码，并在conf/accumulo-site.xml中给出了我应该提到的密码。

<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>

在那之后，一切都像魅力一样运转。希望能帮上忙。如有任何疑问，将乐意提供帮助。
