Cassandra误认为是运行作为root

Question

我正尝试在 MyBinder 环境中运行 Cassandra。在本地它工作得很好。然而，在 MyBinder 上，Cassandra 错误地认为它是运行ning 作为 root。

它具有相同的 java 版本，OS，等等

关于为什么会出现这种行为有什么想法吗？

谢谢！

Running Cassandra as root user or group is not recommended - please start Cassandra using a different system user.
If you really want to force running Cassandra as root, use -R command line option.

jovyan@jupyter-2dx66bgrd2:~/apache-cassandra-4.0-beta1$ ./bin/cassandra -R

问题是当运行宁 id -u 或 id -g 在 [=14] 时，启动脚本认为它是运行作为 root 用户=] (here):

if [ "`id -u`" = "0" ] || [ "`id -g`" = "0" ] ; then
    echo "Running Cassandra as root user or group is not recommended - please start Cassandra using a different system user."
    echo "If you really want to force running Cassandra as root, use -R command line option."
    exit 1
fi

我想 MyBinder 中的 id 命令 return 0 会混淆启动脚本。这不是我们测试的场景，因此可能通过禁用 shell 脚本中的检查来解决它。干杯！
