我正在使用以下配置单元查询:
this.queryExecutor.executeQuery("Drop table user")
我得到以下例外情况:

我看到这里和这里都有类似的帖子,但他们到现在都没有任何回应。我也看了这里,但不认为这是一个有效的行动方案在我的情况。
有趣的是,当我们尝试使用drop table(或drop table,如果存在)查询时,这是特定的。
希望找到解决方法。

据我所知,上述错误可能是因为在不同的jar问题中发现了具有相同包结构的示例类,即:“javax.ws.rs.ext.runtimedelegate”。类对象是在运行时创建和强制转换的。因此,在负责触发drop语法的代码中,由于在类路径中多次找到上述类,因此很有可能会使用并破坏上述类。
我已经尝试过drop and drop if exists in chd5,并且没有问题,下面是我运行的详细信息:
第一次运行-hadoop版本-2.6、hive 1.1.0和spark-1.3.1(包括spark lib的配置单元库)第二次运行-hadoop版本-2.6、hive 1.1.0和spark-1.6.1模式的运行-cli
如果可能,请使用不同版本的spark lib验证drop命令以缩小问题范围。
同时,我正在分析jar以找出存在两个相同类runtimedelegate的链接,并将返回以检查删除任何jar是否可以解决问题,添加jar应重新创建相同的问题。
