自从Hive0.13.0开始,使用HiveServer2 的jdbc方式创建udf的临时函数的方法由:
ADD JAR ${HiveUDFJarPath}
create TEMPORARY function md5 as ‘com.hugedata.hive.udf.codec.UDFMd5‘;
改为:
create TEMPORARY function md5 as ‘com.hugedata.hive.udf.codec.UDFMd5‘ USING JAR ${HiveUDFJarPath};
万恶的这个修改,让我忙活了大半天。
异常堆栈跟踪信息:
Exception in thread "main" java.sql.SQLException: Error while processing statement: null
at org.apache.hive.jdbc.Utils.verifySuccess(Utils.java:120)
at org.apache.hive.jdbc.Utils.verifySuccessWithInfo(Utils.java:108)
