1 我创建了带有自定义UDF功能的jar并将jar复制到 dynamic.jar.dir 中,因此当我将我的UDF函数用作SELECT的一部分时我没有问题就得到了结果。

2 但是当函数是WHERE子句的一部分时,我得到的错误是我找不到自定义函数的类。

select PK FROM "my.custom.view" where MY_FUN(ARRAY["COLF"."COL1"], 'SOMEPARAM')  limit 1;

手动添加jar:

hdfs dfs -copyFromLocal -f /my.jar hdfs:///user/hbase/lib/my.jar

使用以下函数创建函数:

CREATE FUNCTION MY_FUN(BINARY[], VARCHAR) RETURNS BOOLEAN as 'com.myCompany.phoenix.MyCustomFunction' using jar 'hdfs://localhost:57000/user/hbase/lib/my.jar';

我从4.7升级到Phoenix 5.0时遇到了类似的情况。我得到一个异常,指出由于权限问题,我现在需要将UDF .jar放入/ apps / hbase / data / lib中。在旧环境中,我可以使用/ apps / hbase / lib目录逃脱。也许您也正在发生这种情况,但这并不是在提醒您新的路径更改。
