Since you don't want to use any, you could try something like this for the factory (inner) function, using additional method type parameters and a type intersection:

Hi I am facing a problem related to pyspark, I use df.show() it still give me a result but when I use some function like count(), groupby() v..v it show me error, I think the reason is that 'df' is too large.

You're using a wildcard in your path '/mnt/raw_data/play/log_stream/playstats_v100/topic=play_map_play_vod/date=2021-01*', so probably one of them is corrupted. show doesn't throw any error that's mean the path of the records is shown basically correct, but not all of them. You can debug which one is causing the error by checking paths one by one (or few at the time)

Nullpointerexception in AWS Glue on dataframe_obj.count()

Asked 2021-May-14 at 11:28

Good day

I am writing a Glue job on AWS to transform data. After doing a join on two sets of data (resulting in a dataframe of around 100MB in size), I get a Nullpointer exception when retrieving the count on the dataframe. What makes this bug difficult to trace is that it only happens sporadically - occasionally it succeeds.

The error is:

ANSWER

Answered 2021-May-14 at 11:28

In case someone also runs into this. It can happen the moment the data gets "collected". So on writing out a partition of data, getting counts, etc.

The solution is to increase the maximum number of workers. Changing ours from 4 to 25 solved the issue.

ANSWER

Answered 2021-May-06 at 14:51

I'm quite sure what happens here is that the deco_name is interpreted before object initialisation. Pretty much what happens when you annotate a function in a class is that that decorator is "prepared" once the class itself is interpreted, meaning that @deco is unchangable by the time you assign g.

The best option would probably be to just package hello in a different function which fulfills the function of the decorator:

PyFlink: called already closed and NullPointerException

Asked 2021-Apr-16 at 09:32

I run into an issue where a PyFlink job may end up with 3 very different outcomes, given very slight difference in input, and luck :(

The PyFlink job is simple. It first reads from a csv file, then process the data a bit with a Python UDF that leverages sklearn.preprocessing.LabelEncoder. I have included all necessary files for reproduction in the GitHub repo.

To reproduce:

conda env create -f environment.yaml
conda activate pyflink-issue-call-already-closed-env
pytest to verify the udf defined in ml_udf works fine
python main.py a few times, and you will see multiple outcomes

There are 3 possible outcomes.

Outcome 1: success!

It prints 90 expected rows, in a different order from outcome 2 (see below).

Outcome 2: call already closed

It prints 88 expected rows first, then throws exceptions complaining java.lang.IllegalStateException: call already closed.

Regarding outcome 2, it is because the input date (see below) has double quotes. Handling the double quotes properly will fix the issue.

QUESTION

Calling a decorated function correctly

Asked 2021-Apr-15 at 17:26

I'm trying to repeatedly call a decorated function from within another class, such that the decorator is executed everytime the function is called.

The original question is below but does not explicitly relate to pyqt as pointed out correctly.

I'm trying to use decorators within a pyqt thread. From how I understand decorators, the decoration should be executed every time the function is called. (Or at least that is what I want.) However, calling a decorated function from within a pyqt thread leads to execution of the decorator only once.

This is my tested example:
