1-word_count.py运行报错
当我运行：
docker-compose exec jobmanager ./bin/flink run -py /opt/examples/1-word_count.py
报错：

尝试过将python切换成python3，没有解决问题，有没有人遇到同样错误的？
dockerignore stat ./flink-1.13.0 does not exist

ubuntu上运行示例失败，放到本地windows环境运行3-udf_add报错，不太明白什么原因，麻烦帮忙看一下
修改了文件位置，代码如下：
报错如下：
应该是udf函数的原因，去掉的话程序正常运行，如程序的最后改成下面的：

Pyflink 1.11 suport
I noticed there are better enchainment for Flink 1.11 especially for Kubernetes deployment. Is it possible upgrade current playground to support flink 1.11 version?
I am looking forward to get your feedback soon.

Examples using file system fail - Permission Denied
When trying to run the examples that use the file system as a sink I get permission errors:
Caused by: java.io.FileNotFoundException: /opt/examples/data/word_count_output (Permission denied)
This happens for examples 1,3 and 4.
But the other examples work fine, (i.e. 5-word_count-mysql.py ).
I have not done anything other than docker-compose up and run the example code.
It looks like the flink user, which the java process runs as does not have access ot the mounted volumes.

Can we do multiprocessing or distributed computing through PyFlink?
I am trying to get about 14million data and want this process to work faster.Is there any way PyFlink could help?
请问hbase-fat.jar包含些什么内容？
Is there a open to use license on the image
I do not see an open to use license on the image - I am doing a POC with PYFLINK and found the image to be exactly sufficing my use case - hence checking if this image could be used and does this have an open source license ? Please could it be possible to add the license in the repo and the image on docker.
执行pyflink报错 py4j.protocol.Py4JError
py4j.protocol.Py4JError: org.apache.flink.streaming.api.utils.PythonTypeUtils.getCollectionInputFormat does not exist in the JVM
我不知道这种报错到底什么意思，初学者，py文件如下：
from pyflink.common.typeinfo import Types
from pyflink.datastream import StreamExecutionEnvironment
def data_stream_api_demo():
env = StreamExecutionEnvironment.get_execution_environment()
env.set_parallelism(4)
ds = env.from_collection(collection=[(1, 'aaa|bb'), (2, 'bb|a'), (3, 'aaa|a')],type_info=Types.ROW([Types.INT(), Types.STRING()]))
def split(s):
splits = s[1].split("|")
for sp in splits:
yield s[0], sp
ds = ds.map(lambda i: (i[0] + 1, i[1])).flat_map(split).key_by(lambda i: i[1]).reduce(lambda i, j: (i[0] + j[0], i[1]))
ds.print()
env.execute()
if name == 'main':
data_stream_api_demo()
应该是我使用的有问题

Example table/2-from_kafka_to_kafka.py reads from Kafka topic "Rides" but nothing writes to that topic?
The example program reads from a Kafka topic named "Rides". However, there is no code for a producer to write messages to that topic. Is there supposed to be a producer in the playground repo or does the user need to produce these messages?
