1我创建了带有自定义UDF函数的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
的一部分时,我得到的结果没有问题。
2但是当函数是WHERE
子句的一部分时,我得到错误,我的自定义函数的类没有找到。
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
用于创建函数:
CREATE FUNCTION MY_FUN(BINARY[], VARCHAR) RETURNS BOOLEAN as 'com.myCompany.phoenix.MyCustomFunction' using jar 'hdfs://localhost:57000/user/hbase/lib/my.jar';
当我从4.7升级到Phoenix 5.0时,我碰到了类似的东西。我得到一个例外,说明由于权限问题,我现在需要将我的UDF .jar放入/ apps / hbase / data / lib。在旧环境中,我能够使用/ apps / hbase / lib目录逃脱。也许这也发生在你身上,但它没有提醒你新的路径变化。
