我已经用自定义的udf函数创建了jar，并将jar复制到dynamic.jar.dir中，所以当我使用我的udf函数作为 SELECT 我得到的结果没有问题。
但是当函数是 WHERE 子句i获取错误：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

对于函数创建，使用：

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