QUESTION
I have a set of tests that I have implemented on my code base that seems to not being executed and passing nevertheless. As a corollary, Jacoco code coverage is not reporting any execution for these test. This is an example of the problem.
...ANSWER
Answered 2020-Nov-02 at 10:16To run it, you have to run it by pipeline.run()
. Add it in your test method as the following and try again please.
QUESTION
I am trying to have a PCollection of AutoValue-defined objects that I have created, and I've added the appropriate annotations to infer the Schema via DefaultSchema(AutoValueSchema.class)
. Like so:
ANSWER
Answered 2020-May-28 at 23:32This error occurs because ByteBuddy and the Java reflection utilities are not able to infer the parameter names of your @SchemaCreate
method (thus complaining about some unknown parameter arg0
- this is the default name).
To ensure Java reflection can find the parameter names, you need to instruct the compiler to include this information. If you are building with Maven, you can do it this way:
QUESTION
I'm trying to build a unit test for my pipeline.
This pipeline read from pubsub, perform a transformation and write the result to pubsub again.
To simplify even more the unit test until it works, the unit test will only receive a string as an input and test if the output is the some string.
The code looks like the following:

Answered 2019-Dec-17 at 07:40First of all I removed the JUnit library which I installed through maven (Properties -> Java Build Path -> Libraries -> Add Library -> JUnit -> Junit 3/4/5)
After that, in the pom file I added the Junit dependency (also de hamcrest which I added previously):
QUESTION
I am attempting to recreate a simple example of the apache beam pipeline described in this blog post, which makes use of state and timers.
I have written this code to try and test what is in the blog post. The code should simply enrich string records by appending ": enrich" to each record. Before I could add the "stale" timer, I got an error.
I am using apache beam version 2.13, and the direct runner.
Here is the Enrich DoFn that is mostly copy pasted from the blog:
...ANSWER
Answered 2019-Aug-07 at 14:46In the end, I edited the onExpiry
to use context.outputWithTimestamp(enrichEvent(event), window.maxTimestamp());
instead of context.output(enrichEvent(event));
. This solved the problem.
Here is the corrected onExpiry
method.
QUESTION
I'm in the process of writing a simple test to verify the semantics of early/on-time/late panes. The pipeline combines the number of elements per key. My early and on-time panes are working as expected, though my final pane seems to be empty at all times.
...ANSWER
Answered 2019-May-15 at 22:44FinalPane is different from LatePane.
FinalPane is expected to be empty in your testing because your test case fires trigger for each element, thus there is NO ONE left behind to be in FinalPane.
Your intention, as I can read from comments, is correct, to test against LatePane. For unknown reason this particular case of LatePane is missing in PAssert util function list. I made a PR to fix this: https://github.com/apache/beam/pull/8587
QUESTION
I have a PCollection which I am certain contains:
- "Bob"
- "John"
- "Fred"
However, when I test an assertion that asks if "Bob" is in the PCollection using:
...ANSWER
Answered 2019-Apr-27 at 16:48The containsInAnyOrder()
function is used to determine that the source PCollection contains all the items and not just a subset of the items. Don't think of this as "Does it contain the elements I listed?" but rather think of it as "Is this PCollection completely made up of all the elements I listed (but in any order)".
QUESTION
I am trying to trying to write a Beam Streaming pipeline, that simply reads from a PubSub Queue, parses the data and writes to either one of two BigQuery Tables. So code takes advantage of side outputs to write to one of two tables from within the DoFn. I am running into the following error message: java.lang.IllegalArgumentException: unable to serialize DoFnAndMainOutput{doFn=com.pipeline.PubSubToBigQuery$ParsePubSubMessage@50eca7c6, mainOutputTag=Tag}. I will attach the full error message, DoFn and Test class below:
DoFn:
...ANSWER
Answered 2019-Jan-14 at 19:52The problem is in the log: java.io.NotSerializableException: com.pipeline.PubSubToBigQueryTest
. Make your test implement Serializable
, this should solve it. Or try moving all the DoFns
and other in-line functionality into separate serializable classes.
QUESTION
I may be missing something obvious, but for some reason I can't make PAssert
& TestPipeline
work with CoGroupByKey
-- but without it, it works fine.
Here is a reference test file that can reproduce the issue I'm facing. I tested with both beam sdk 2.4 and 2.5.
For comparison, testWorking
works as intended, and testBroken
has an additional step like this:
ANSWER
Answered 2018-Sep-17 at 18:54THe root cause from the exception is 'java.io.NotSerializableException: exp.moloco.dataflow2.ReferenceTest'. Some of the objects are inadvertently holding reference to the outer class 'ReferenceTest'. Those are most likely the anonymous classes defined for TupleTags. Please try making them regular classes.
QUESTION
I am writing a pipeline that is processing product events (create, update, delete). Each product belongs to a sale that has a certain duration. I want to be able to perform some aggregation on all the products in a given sale. For the purpose of this example, let's assume I just want a list of unique product IDs per sale.
Therefore, my pipeline is using session windows on the sale id with a very long gap duration (so when the sale closes and there are no more product updates being published, the window for that sale closes too). My question is, how do I write a unit test for that?
For the sake of this test, let's assume the following:
- the events are just Strings with the sale ID and the product ID, separated by a space,
- the
applyDistinctProductsTransform
will basically perform what I've said above. CreateKV
elements where the key is the sale id; set session windows with a gap duration of 600 seconds; and finally create a concatenated string of all product IDs per sale.
Here is what I have so far:
I create a TestStream
and add some elements: 3 products for sale1
. Next, I advance the watermark to 700, well beyond the gap duration. Another product is added and finally the watermark is advanced to infinity.
ANSWER
Answered 2018-Aug-24 at 17:401) I believe you have a simple unit issue. The window gap duration of 600 is being specified in seconds Duration.standardSeconds yet new Instant(long) uses milliseconds which means that the 600 second gap is larger then the time interval of 700 millis causing the sessions to be merged.
2) Sessions still use interval windows internally. You will need to compute what the output window would be after all sessions are merged based upon your trigger strategy. By default, a session window uses the IntervalWindow(timestamp, gap duration), and merges all overlapping windows to create a larger window. For example, if you had the windows (start time, end time), [10, 14], [12, 18], [4, 14] for the same session key, they would all be merged producing a single [4, 18] window.

I am attempting to use Apache Beam from Java as a data pipeline of sorts. I have written a simple class that sources from Google Pubsub and sinks to Google Bigquery, but I cannot get it to build for the life of me. I am using Maven to build and have added every Beam package I could find, but I still get "class file not found" errors.
