Flink Runner logging FAILED_TO_UNCOMPRESS

2019-09-14 Thread Yu Watanabe
Hello.

I am trying to spin up the flink runner but looks like data serialization
is failing.
I would like to ask for help to get over with this error.

Try adding "--experiments=beam_fn_api" to your pipeline options. (This is a
known issue with Beam 2.15 that will be fixed in 2.16.)

Thank you for the assistance.

By specifying "experiments" in PipelineOptions ,
==
options = PipelineOptions([
  "--runner=FlinkRunner",
  "--flink_version=1.8",
  "--flink_master_url=localhost:8081",
  "--experiments=beam_fn_api"

I was able to submit the job successfully.

Re: Flink Runner logging FAILED_TO_UNCOMPRESS

2019-09-17 Thread Maximilian Michels

+dev

The beam_fn_api flag and the way it is automatically set is error-prone. 
Is there anything that prevents us from removing it? I understand that 
some Runners, e.g. Dataflow Runner have two modes of executing Python 
pipelines (legacy and portable), but at this point it seems clear that 
the portability mode should be the default.


Cheers,
Max

+1 for making --experiments=beam_fn_api default.

Can the Dataflow runner driver just remove the setting if it is not
compatible?

The tricky bit would be undoing the differences in graph construction
due to this flag flip. But I would be in favor of changing the default
(probably just removing the flag) and moving the non-portability parts
into the dataflow runner itself. (It looks like the key differences
here are for the Create and Read transforms.)

Re: Flink Runner logging FAILED_TO_UNCOMPRESS

2019-09-17 Thread Kyle Weaver
The flag is automatically set, but not in a smart way. Taking another look
at the code, a more resilient fix would be to just check if the runner
isinstance of PortableRunner.

Re: Flink Runner logging FAILED_TO_UNCOMPRESS

2019-09-17 Thread Maximilian Michels

Is not this flag set automatically for the portable runner


Yes, the flag is set automatically, but it has been broken before and 
likely will be again. It just adds additional complexity to portable 
Runners. There is no other portability API then the Fn API. This flag 
historically had its justification, but seems obsolete now.


An isinstance check might be smarter, but does not get rid of the root 
of the problem.

The tricky bit would be undoing the differences in graph
construction
due to this flag flip. But I would be in favor of changing
the default
(probably just removing the flag) and moving the
non-portability parts
into the dataflow runner itself. (It looks like the key
differences
here are for the Create and Read transforms.)

I disagree that this flag is obsolete. It is still serving a purpose for
batch users using dataflow runner and that is decent chunk of beam python
users.

I agree with switching the default. I would like to give enough time to
decouple the flag from the core code. (With a quick search I saw two
instances related to Read and Create.) Have time to test changes and then
switch the default.

I might be wrong, IIUC, it will temporarily resolve the reported issues. Is

Re: Flink Runner logging FAILED_TO_UNCOMPRESS

2019-09-18 Thread Maximilian Michels

I disagree that this flag is obsolete. It is still serving a purpose for batch 
users using dataflow runner and that is decent chunk of beam python users.


It is obsolete for the PortableRunner. If the Dataflow Runner needs this 
flag, couldn't we simply add it there? As far as I know Dataflow users 
do not use the PortableRunner. I might be wrong.


As Kyle mentioned, he already fixed the issue. The fix is only present 
in the 2.16.0 release though. This flag has repeatedly caused friction 
for users and that's why I want to get rid of it.


There is of course no need to rush this but it would be great to tackle 
this for the next release. Filed a JIRA: 
https://jira.apache.org/jira/browse/BEAM-8274

Max

Yes, the flag is set automatically, but it has been broken
before and
likely will be again. It just adds additional complexity to
portable
Runners. There is no other portability API then the Fn API. This
flag
historically had its justification, but seems obsolete now.


I disagree that this flag is obsolete. It is still serving a purpose
for batch users using dataflow runner and that is decent chunk of

I agree with switching the default. I would like to give enough time
to decouple the flag from the core code. (With a quick search I saw
two instances related to Read and Create.) Have time to test changes
and then switch the default.


An isinstance check might be smarter, but does not get rid of
the root
of the problem.


I might be wrong, IIUC, it will temporarily resolve the reported
issues. Is this not accurate?

Re: Flink Runner logging FAILED_TO_UNCOMPRESS

2019-09-18 Thread Ahmet Altay
I believe the flag was never relevant for PortableRunner. I might be wrong
as well. The flag affects a few bits in the core code and that is why the
solution cannot be by just setting the flag in Dataflow runner. It requires
some amount of clean up. I agree that it would be good to clean this up,
and I also agree to not rush this especially if this is not currently
impacting users.

Re: Flink Runner logging FAILED_TO_UNCOMPRESS

2019-09-19 Thread Maximilian Michels
The flag is insofar relevant to the PortableRunner because it affects 
the translation of the pipeline. Without the flag we will generate 
primitive Reads which are unsupported in portability. The workaround we 
have used so far is to check for the Runner (e.g. PortableRunner) during 
pipeline translation and then add it automatically.


A search in the Java code base reveals 18 occurrences of the flag, all 
inside the Dataflow Runner. This is good because the Java SDK itself 
does not make use of it. In portable Java pipelines the pipeline author 
has to take care to override primitive reads with the JavaReadViaImpulse 
wrapper.


On the Python side the IO code uses the flag directly to either generate 
a primitive Read or a portable Impulse + ParDoReadAdapter.


Would it be conceivable to remove the beam_fn_api flag and introduce a 
legacy flag which the Dataflow Runner could then use? With more runners 
implementing portability, I believe this would make sense.


Thanks,
Max

This is obviously less than ideal for the user... Should we "fix" the
Java SDK? Of is the long-terms solution here to have runners do this

Re: Flink Runner logging FAILED_TO_UNCOMPRESS

This is obviously less than ideal for the user... Should we "fix" the
Java SDK? Of is the long-terms solution here to have runners do this
rewrite?


I think ideal would be that the Runner adds the Impulse override. That 
way also the Python SDK would not have to have separate code paths for 
Reads.

does not make use of it. In portable Java pipelines the pipeline author
has to take care to override primitive reads with the JavaReadViaImpulse
wrapper.

On the Python side the IO code uses the flag directly to either generate
a primitive Read or a portable Impulse + ParDoReadAdapter.

Would it be conceivable to remove the beam_fn_api flag and introduce a
legacy flag which the Dataflow Runner could then use? With more runners
implementing portability, I believe this would make sense.

It requires some amount of clean up. I agree that it would be good to
clean this up, and I also agree to not rush this especially if this is
not currently impacting users.

 It is obsolete for the PortableRunner. If the Dataflow Runner needs
 this
 flag, couldn't we simply add it there? As far as I know Dataflow users
 do not use the PortableRunner. I might be wrong.

 As Kyle mentioned, he already fixed the issue. The fix is only present
 in the 2.16.0 release though. This flag has repeatedly caused friction
 for users and that's why I want to get rid of it.

 There is of course no need to rush this but it would be great to tackle
 this for the next release. Filed a JIRA:
 https://jira.apache.org/jira/browse/BEAM-8274

Or, rather, that the Runner adds the non-Impuls override (in Java and Python).
