所以我已经按照accumulo用户手册中的规定配置和初始化了accumulo。
在conf/accumulo-site.xml中，我将trace.user设置为accumulo_tracer，并且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，一切都启动正常，包括accumulo UI。但是在logs/tracer_localhost.log文件中显示如下错误:

任何帮助或指导，我可能错过了一些东西，将是非常有帮助的!提前感谢!
您不需要使用该名称创建系统用户。您需要的是创建一个具有该名称的Accumulo用户。您可以在accumulo shell中以(accumulo)根用户$ACCUMULO_HOME/bin/accumulo shell -u root的身份执行此操作。您还需要授予用户创建表的表权限。查看shell中的help grant，了解如何为该用户设置CREATE_TABLE系统权限。
所以这就是解决我的问题:一个新的init!!
因此，在init阶段，我为root用户提供了一个密码，该密码与我应该在conf/accumulate -site.xml 中提到的密码相同。<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>
从那以后，一切都很顺利。希望这对你有所帮助。张贴任何疑问，将很乐意提供帮助。
