UDx RPC调用InvokeGetUdxType（）问题中的R函数失败

我试图在Vertica中创建一个R函数，但我得到了一个错误。 任何帮助或线索都将受到高度重视

dbadmin=> create transform function pred as language 'R' name 'pred' library predLb;
ROLLBACK 3399:  Failure in UDx RPC call InvokeGetUdxType(): Error calling getUdxType() in User Defined Object [predict] at [/scratch_a/release/16125/vbuild/vertica/OSS/UDxFence/vertica-udx-R.cpp:209], error code: 0, message: Error happened in getUdxType : Exception in processing required attribute udxtype in the factory function : no applicable method for 'predict' applied to an object of class "NULL"

找到了答案！ 实际上，R libs没有什么问题，只是拼写问题（，对我来说不是。我不检查R Udx代码。 R函数名为pred，但不同。

R函数名为pred是不同的。

您尝试过Vertica社区吗？这是在社区版本上运行的！这可能是问题所在吗？我只是不认为很多HP人员都在关注StackOverflow。事实上，我已经在HP的R论坛上发布了相同的内容，他们帮了我。您尝试过Vertica社区吗？这是在comm上运行的unity版本！这可能是问题所在吗？我只是不认为有多少HP人员关注StackOverflow。事实上，我已经在HP的R论坛上发布了同样的内容，他们帮助了我。
