this is ok to test.

tdas · 2015-10-20T23:22:31Z

@zsxwing can you take a look.

Test build #44014 has finished for PR 9186 at commit aa87c40.

This patch fails PySpark unit tests.
This patch merges cleanly.
This patch adds the following public classes (experimental):\n * class StreamingListener(object):\n

djalova · 2015-10-21T00:01:55Z

The test that failed was a flaky StreamingKMeansTest.
Please retest.

tdas · 2015-10-21T01:00:41Z

test this again

djalova · 2015-10-21T18:50:41Z

@tdas it looks like Jenkins didn't retest

Test build #44115 has finished for PR 9186 at commit aa87c40.

This patch passes all tests.

This patch adds no public classes.

Is this method necessary?

I thought it would make it easier to see which Info is associated with each StreamingListenerEvent but I can remove it.

Would it be better to use this method to return instances of the Python friendly classes for these Scala objects?

zsxwing · 2015-10-22T06:56:54Z

I suggest adding some Python friendly classes for BatchInfo, ReceiverInfo, OutputOperationInfo and converting these Scala objects to them. Some Scala things, like Scala Map, Option, are hard to use in Python.

… ReceiverInfo

djalova · 2015-10-24T00:10:18Z

The listener sometimes receives 3 batchCompleted events instead of 4 when I run the test, even though it always gets the correct job output. However, when I add a minor delay the test passes consistently. Can I get someone's opinion on this?

Take a look at PySparkStreamingTestCase.wait_for. You can use it to wait for the expected results or timeout.

zsxwing · 2015-11-12T06:49:33Z

I just meant you can access the Map here, e.g.:

for streamId in info.streamIdToInputInfo(): streamInputInfo = info.streamIdToInputInfo()[streamId] # access fields of streamInputInfo for outputOpId in info.outputOperationInfos(): outputOperationInfo = info.outputOperationInfos()[outputOpId] # access fields of outputOperationInfo

zsxwing · 2015-11-12T06:52:38Z

I just noticed that Streaming Python unit tests cannot report failure. It always says pass even if some test fails. Investigating it.

zsxwing · 2015-11-12T18:46:54Z

We should retest this PR after merging #9669.

tdas · 2015-11-13T08:31:59Z

@djalova could you fix the test?

zsxwing · 2015-11-13T22:40:52Z

@djalova could you add the following checks?

I just meant you can access the Map here, e.g.:

for streamId in info.streamIdToInputInfo():
streamInputInfo = info.streamIdToInputInfo()[streamId]
# access fields of streamInputInfo

for outputOpId in info.outputOperationInfos():
outputOperationInfo = info.outputOperationInfos()[outputOpId]
# access fields of outputOperationInfo

zsxwing · 2015-11-13T23:13:16Z

Sorry for my unclear comment. I just meant adding the real codes to access fields of streamInputInfo and outputOperationInfo, such as

streamInputInfo.inputStreamId()
streamInputInfo.numRecords()
for key in streamInputInfo.metadata():
    streamInputInfo.metadata()[key]
metadataDescription.metadataDescription()
...

djalova · 2015-11-13T23:40:46Z

Sorry I wasn't reading your comment carefully. I'll make the update.
