如何修复Apache Ignite中“无法初始化类org.Apache.ignite.igniteJDBCTHINDriver”错误？

Question

我正在尝试使用Apache Ignite内置工具SQLLine连接到Apache Ignite服务器。我得到错误:java.lang.noClassDefFounderRor:无法初始化类org.apache.ignite.igniteJDBCTHINDriver

我让Apache Ignite在一个容器中运行，CentOS7在另一个容器中运行。在同一网络中运行的两个容器（ping是双向的）。尝试的连接发生在从CentOS7到Apache Ignite之间。

我应该能够用连接到我的Ignite服务器！在SQLLine中连接jdbc:Ignite:Thin://172.19.0.2/命令。这不起作用，并且throws无法初始化类org.apache.ignite.IgniteJDBCThinDriverIgniteJDBCThinDriver已安装/可用。

建议使用Java8，因为Apache Ignite 2.7.0不完全支持Java12。否则，您可以尝试对JVM选项进行修修补补。
