有什么办法可以在S3中获得Awsglue Libs？

Question

我正在运行许多具有相同代码的胶水作业，所以我认为我会以S3桶移动代码，并将其称为common_code.py，然后从胶水作业中调用它。但是我在运行它时遇到了问题。我遇到错误的行是

df = spark.read \
            .format("JDBC") \
            .option("url", postgresURL) \
            .option("driver", postgresDriver) \
            .option("header", "true") \
            .option("query", "select max(job_id) as job_id from public.job_execution_detail") \
            .option("user", user) \
            .option("password", password) \
            .load()

错误的 -

我认为代码无法导入AWSGLUE LIB或PYSPARK LIB。这只是我的想法，但是有什么建议吗？

Answer 1

它与我的common_code.py无关，我在连接到数据库时实际上搞砸了。我通过了错误的论点，并痛苦地了解到了这一点。
