Re: 【PyFlink】对于数据以Csv()格式写入kafka报错,以及使用python udf时无法启动udf

jincheng sun
彭哲夫,你好:

你是如何安装的beam,安装的版本是多少?如果是1.10 需要apache-beam 2.15,如果是 master需要apache-beam
2.19.

BTW,  为了共享你的问题,我将你的问题发到了中文用户列表里面,我们大家一起讨论。

Best,
Jincheng

Re: 【PyFlink】对于数据以Csv()格式写入kafka报错,以及使用python udf时无法启动udf

jincheng sun
Hi Zhefu,

谢谢您分享解决问题的细节,这对社区有很大的贡献!

1. 关于订阅问题

我想确认一下,你是否参考了[1],同时以订阅中文用户列表([hidden email])为例,您需要发送邮件到([hidden email]),就是在原有邮件的地址上添加subscribe。同时收到一封“confirm subscribe to user-zh@flink.apache.org”的确认邮件,需要进行确认回复。

2. 关于JAR包冲突问题

flink-python JAR会携带flink-python对beam依赖的核心JAR包,我这里想了解一些,为啥你集群上面存在这beam相关的包?另外我认为您提供的case很好,让我想到了可以对PyFlink对Beam的依赖进行一些优化,比如将beam进行relocation. 我已经创建了社区改进JIRA[2].

3. 关于打包问题

上传给PyFlink的Python环境包需要是在机器间可移植的,所以的确不能包含软链接。如果是用virtualenv创建的环境的话,需要加上--always-copy选项。此外,如果集群机器上已经有准备好的python3.5+的环境,可以不用上传环境包,直接使用add_python_executable("python3")为集群指定要使用的Python Interpreter。
除了virtualenv,conda/miniconda 也可用于创建虚拟环境,但是大小要大很多,在virtualenv处于某些原因不work的时候(比如源python解释器依赖的so文件在集群上不存在),可以考虑使用。

再次感谢您分享问题的解决细节和问题的反馈!

Zhefu PENG <[hidden email]> 于2020年3月24日周二 下午9:33写道:
Hi Jincheng,

在中文邮件用户列表里我无法回复自己的问题(我已经十分确认subscribe了mailing list, but i dont know why and how),所以在这里回复一下。 经过同事的帮忙和共同努力,我们初步解决了之前的疑问。反馈如下:

1. 首先是包冲突的问题,我们发现flink-python这个包下也有beam-runners-core-java-2.15.0.jar,  beam-runners-direct-java-2.15.0.jar,  beam-runners-flink_2.11-2.15.0.jar, beam-sdk-java-core-2.15.0.jar这四个jar包的代码,若是运行的集群环境下本身也有这四个包的话,则会产生冲突,运行udf功能时找不到依赖。

2. 因为一些原因,集群的python默认环境无法改成python3,因此我们在代码中添加env.add_python_archive的功能,并且使用set_python_executor来帮助指定解释器。 用到的压缩包,在打包时一定要去掉软链接的使用,(可能在解压后不支持软链接查找。),我之前打包方式有错,所以出现了问题。

以上两点是我们排查出的原因,也终于能在cluster mode下成功运行udf。希望我们的反馈也能给你们的发展以及对用户的指导增加一点贡献。再次感谢帮助:)

Best,
Zhefu

Zhefu PENG <[hidden email]> 于2020年3月20日周五 下午11:19写道:

感谢回复!beam就是直接用pip install方法安装的,因为在用pip install apache-flink的时候发现有很多依赖,而且在安装时候要求安装beam的2.15.0的版本,我就安上了2.15.0。flink版本是1.10,没有从源码编译。因此我们也很困扰现在,希望能够求得帮助。

还有个小问题,就是我看到似乎你没有把日志一起转到邮件列表中,我想附带上去,那么我在订阅后,直接回复可以把日志贴上去吗?

顺祝,周末愉快:)非常感谢回复!

Hi Jincheng,

针对昨天提到的第二点,我做了两个思路:1. 将我的pyflink.py以本地模式运行,2.对集群节点进行环境配置

1. 在本地模式中,我们发现在装apache-beam包的时候出于某些原因没有装全,少了_bz2模块,再补充上之后,pyflink.py的脚本可以正常运行,其中的udf功能也能正常使用。

2. 在本地模式运行成功的基础上,我们根据你的建议,对所有的worker节点进行了环境的更新,都更新到了python3.6以及安装了apache_beam和apache-flink. 但是以集群模式运行带有udf功能的脚本仍然报错,尝试谷歌搜索以后也没有搜到相关解答,在附件附上错误日志,希望能得到帮助(因为本地模式已经成功所以就不附带代码了),非常感谢!

你好:

在网上看到了你的博客,关于你对pyflink的开发和推动深感敬佩。我们部门因为业务需要最近在调研使用flink相关,我写了个一个简单的demo想做体验和测试,但是遇到了两个问题(第二个问题是目前遇到的比较大的困难,第一个问题采取了规避策略:)):

1. 当我把数据想以Csv格式输出到Kafka时,报错。(从社区文档我已经了解到应该用Csv()取代OldCsv(),并修改)。查看报错信息后我怀疑是因为缺少jar包导致(比如之前使用Json格式时候),但是从另一个文档中了解到csv格式应该是built-in的。目前采取了规避措施,采用json格式输出。

报错信息如下:

py4j.protocol.Py4JJavaError: An error occurred while calling o62.insertInto.
: org.apache.flink.table.api.NoMatchingTableFactoryException: Could not find a suitable table factory for 'org.apache.flink.table.factories.SerializationSchemaFactory' in

Reason: No factory supports all properties.

The matching candidates:
org.apache.flink.formats.csv.CsvRowFormatFactory
Unsupported property keys:
format.fields.#.name
format.fields.#.data-type

table注册部分代码如下:
table_env.connect(Kafka()
                  .version("universal")

                  .property(kafka_server, ','.join(kafka_server_list))

                 .field("b", DataTypes.STRING())
                 .field("c", DataTypes.STRING())) \
    .create_temporary_table(table_name_output)

2.采用规避策略后,尝试使用python udf增加自定义的函数丰富功能。但是在按照给的demo中的步骤定义好udf函数后, 才运行起来后,一段时间内会超时报错,猜测是因为pyflink-udf-runner.sh这个脚本没有被启用, 但是在所依赖的opt/flink-python_2.11-1.10.0.jar的包内可以找到该脚本。
报错信息如下:

这部分代码如下:
@udf(input_types=[DataTypes.STRING()],
     result_type=DataTypes.STRING())
def if_length_enough(devid):
    res = devid + " func"
    return res

table_env.register_function("if_length_enough", if_length_enough)

Re: 【PyFlink】对于数据以Csv()格式写入kafka报错,以及使用python udf时无法启动udf

lgs
Hi Jincheng,

我现在碰到同样的问题,udf运行的时候会打印这样的log:
2020-08-07 03:06:45,920 INFO
org.apache.beam.runners.fnexecution.environment.ProcessEnvironmentFactory []
- Still waiting for startup of environment
'/usr/local/lib64/python3.6/site-packages/pyflink/bin/pyflink-udf-runner.sh'
for worker id 1-1
然后过一阵就pyflink退出了。

我是用local模式运行的。我的beam版本是2.19 安装最新的2.23也是一样的问题。
apache-flink版本是1.11.0

请问有什么办法可以排查这个错误?

Re: 【PyFlink】对于数据以Csv()格式写入kafka报错,以及使用python udf时无法启动udf

Dian Fu
flink 1.11.0的话,依赖的beam版本是2.19.0,所以先不要用最新的beam 2.23.0

针对你这个问题,应该是在启动过程中,由于某种原因,Python进程启动失败了,常见的原因有:依赖缺失,Python版本不对等等。
按说在log文件里(你发的log信息所在的log文件),应该能看到详细的原因,你的log文件里面没有详细的失败原因吗?

Hi, jincheng.

最近也遇到了类似问题,请问有什么思路吗?

flink-python 的 jar 都是有的,且版本是对的。

版本是 1.11.1,这个主要是在引入了 udf 时出现的,之前是正常的。

尝试过 virtualenv 打包 python 环境也没有效果。

具体报错如下:

Re: 【PyFlink】对于数据以Csv()格式写入kafka报错,以及使用python udf时无法启动udf

Xingbo Huang
Hi,
看报错是NoClassDefFoundError,应该是包冲突了,你是不是自己安装了apache-beam(1.11.1依赖的beam是2.19.0的版本)的其他版本了,亦或者你可以看下是不是PipelineOptions这个beam类依赖的其他包里面存在了包冲突的问题

Best,
Xingbo

Re: 【PyFlink】对于数据以Csv()格式写入kafka报错,以及使用python udf时无法启动udf

jing
This post was updated on .
Hi, xingbo.
在检查之后,并没有发现什么 beam 的其他版本,flink-python 版本是 2.11-1.11.1。不管是 pip install
apache-beam==2.19.0 还是没有,都是一样的问题。
用 udf 的示例代码也不通过。本地 python demo.py 是可以正常的。
只有是 flink run -m localhost:8081 -py demo.py 是一直在出现这种问题。
pyflink-shell.sh remote localhost 8081 也试过了。一样的结果。

在本地 start-cluster.sh 之后,PYFLINK_CLIENT_EXECUTABLE=/usr/local/bin/python3 flink run -py demo.py
也是一样的。

示例代码如下:

import logging
import sys
from pyflink.datastream import StreamExecutionEnvironment
from pyflink.table import StreamTableEnvironment, EnvironmentSettings,
DataTypes
from pyflink.table.udf import udf


def word_count():
    content = "line Licensed to the Apache Software Foundation ASF under one
" \
              "line or more contributor license agreements See the NOTICE
file " \
              "line distributed with this work for additional information "
\
              "line regarding copyright ownership The ASF licenses this file
" \
              "to you under the Apache License Version the " \
              "License you may not use this file except in compliance " \
              "with the License"
    t_env = StreamTableEnvironment.create(
        StreamExecutionEnvironment.get_execution_environment(),
       
environment_settings=EnvironmentSettings.new_instance().use_blink_planner().build()
    )
   
t_env.get_config().get_configuration().set_boolean("python.fn-execution.memory.managed",
True)
    sink_ddl = """
        create table Results(word VARCHAR,`count` BIGINT) with ( 'connector'
= 'print')
        """
    add = udf(lambda i: i + 1024, [DataTypes.BIGINT()], DataTypes.BIGINT())
    t_env.register_function("add_test", add)
    t_env.sql_update(sink_ddl)
    elements = [(word, 1) for word in content.split(" ")]
    t_env.from_elements(elements, ["word", "count"]) \
        .group_by("word") \
        .select("word, add_test(count(1)) as count") \
        .insert_into("Results")
    t_env.execute("word_count")


if __name__ == '__main__':
    logging.basicConfig(stream=sys.stdout, level=logging.INFO,
format="%(message)s")
    word_count()


环境是基于官方的 docker 镜像 flink:1.11.1-scala_2.11,JobManager 和 TaskManager 都正常,在没有
udf 的时候作业都是正常的,jar 包只装了 jdbc,kafka,es 的connector,还有 csv 的 jar 包。

这个情况下需要装什么东西吗,还是需要改配置。

Re: 【PyFlink】对于数据以Csv()格式写入kafka报错,以及使用python udf时无法启动udf

Xingbo Huang
Hi,
1. 之前那个报错在重新安装完pyflink之后有没有解决(本地python
demo.py是否正常);之前那个报错是本地运行就报错,还是在远程提交才报的错。
2. 现在这个报错是作业提交时编译阶段就报错了,还没到作业运行。在作业提交的console界面是可以看到错误日志的,可否提供一下错误日志。

Best,
Xingbo

Re: 【PyFlink】对于数据以Csv()格式写入kafka报错,以及使用python udf时无法启动udf

jing
1. 重新安装之后并没有解决。
本地提交和远程提交都有问题。用 python demo.py 的方式是正常的。
2. 作业是已经提交了。
有在提示 Job has been submitted with JobID 05fcaebfec3aca731df408418ebea80c
然后立马会出现下面的错误:

即:Caused by: java.lang.NoClassDefFoundError: Could not initialize class

Re: 【PyFlink】对于数据以Csv()格式写入kafka报错,以及使用python udf时无法启动udf

Xingbo Huang
Hi,

1. python demo.py运行正常,说明代码和你本地执行的python环境都没有问题。
2. 你现在给的错误和你前一封邮件给的那个编译报错不是一个报错,一个一个问题来。
3.
你这个运行报错是你集群运行环境里面的python环境的beam包冲突了,就是我一开始回答的,你去得去检查集群运行环境里面的python环境是否符合要求。

Best,
Xingbo
