Redshift UDF中的murmur2软件包导入失败

Question

我正在尝试将murmur2软件包作为Redshift数据库中的库导入。我做了以下步骤

1. 运行模块打包程序
   $ ./installPipModuleAsRedshiftLibrary.sh -m murmur2 -s s3://path/to/murmur2/lib

2. 在redshift上创建库
   CREATE OR REPLACE LIBRARY murmur2 LANGUAGE plpythonu from 's3://path/to/murmur2/lib/murmur2.zip' WITH CREDENTIALS AS 'aws_access_key_id=AAAAAAAAAAAAAAAAAAAA;aws_secret_access_key=SSSSSSSSSSSSSSSSS' region 'us-east-1';

3. 创建函数并查询

   create OR REPLACE function f_py_kafka_partitioner (s varchar, ps int)
returns int stable as $$ import murmur2
m2 = murmur2.murmur64a(s, len(s), 0x9747b28c)
return m2 % ps
$$ language plpythonu;

SELECT f_py_kafka_partitioner('jiimit', 100);

这将导致以下错误：

[Amazon](500310) Invalid operation: ImportError: No module named murmur2. Please look at svl_udf_log for more information

这是svl_udf_log的内容
