.jcall中的错误（drv @ jdrv，＆＃34; Ljava / sql / Connection;＆＃34;，＆＃34; connect＆＃34;，as.character（url）[1]，：   java.sql.SQLException：[Simba] HiveJDBCDriver操作无效：无法获取主体名称进行身份验证;

Answer 1

1. make sure kinit is issued and kerberoes ticket is generated using klist
2. right Java version for the given R version (32/64 bit) available on the class-path
3. right slf4j jars available based on your java version

All these steps should resolve the issue assuming your code does not have logic issues.
