Kafka Streaming
I am trying to run the examples from git. While running the wordcount
example I see this error:
Caused by: *java.lang.RuntimeException*: librocksdbjni-win64.dll was not
found inside JAR.
Am I expected to include this jar locally?

I mixed up version numbers... Current CP version is 3.0.1 and not 3.1
Ie. 3.0.1 contains Kafka 0.10.0.1 and 3.1 will be released soon will
contain Kafka 0.10.1.0
examples master uses CP-3.1-SNAPSHOT.
Sorry for the confusion.

Re: Kafka Streaming
Posted by Guozhang Wang <wa...@gmail.com>.
Hello Mohit,
I'm copy-pasting Mathieu's previous email on making Streams to work on
Windows, note it was for 0.10.0.1 but I think the process should be very
similar.
--------
To any who follow in my footsteps, here is my trail:
1. Upgrade to at least Kafka Streams 0.10.0.1 (currently only in RC).
- This is necessary because .1 bumps the rocksdb dependency to 4.8.0,
where the previous 4.4 dependency did not yet support loading a
Windows JNI
library.
2. Follow the instructions here (
https://github.com/facebook/rocksdb/blob/v4.8/CMakeLists.txt) to build
rocksdb.
- That link is for the v4.8 tag; be sure to match this with the
version of rocksdb that Kafka Streams depends upon in the
future. 0.10.0.1
-> v4.8, but future releases of Kafka Streams will likely depend on
newer
versions.
- Be sure to include the "-DJNI=1" compile option to build the JNI
wrapper.
- None of the third-party dependencies (eg. snappy, jemalloc, etc.)
seem to be required to get something functional, but, it
probably isn't the
most efficient build.
- Ensure that "javac" and "javah" are on your path when running
cmake; if there are any errors in the cmake output your JNI wrapper
probably won't build.
- You may or may not need to make minor patches to make the project
build in Windows. It appears that the Windows build is often broken;
for
example, I had to apply this patch:
https://github.com/facebook/rocksdb/pull/1223/files
- Phew, that should give you a build\java\Debug\rocksdbjni.dll. So
close to the summit... just a horrible hack left...
3. Copy rocksdbjni.dll to librocksdbjni-win64.dll.
4. Insert librocksdbjni-win64.dll into your rocksdbjni-4.8.0.jar.
- Ugh, this is the horrible hack. rocksdbjni seems to only look
inside its own jar for its native libraries, so, this is where
it needs to
be.
- If you're a gradle user on Windows, you'd find this jar file
in C:\Users\...your-windows-user...\.gradle\caches\modules-2\
files-2.1\org.rocksdb\rocksdbjni\4.8.0\b543fc4ea5b52ad790730dee376ba0
df06d9f5f7.
And there you go, almost a working Kafka Streams app in Windows. One other
detail is that the default state storage directory doesn't seem to be
created on demand, so I had to mkdir C:\tmp\kafka-streams myself before my
app would work.
------------
Currently we have not spent too much time running and maintaining Kafka
Streams in Windows yet, but we'd love to hear your experience and if there
is any issues come up, we would like to help debugging and fixing them.

Re: Kafka Streaming

Would this be an issue if I connect to a remote Kafka instance running on
the Linux box? Or is this a client issue. What's rockdb used for to keep

Kafka 0.10.1.0 which was release last week does contain the fix
already. The fix will be in CP 3.1 coming up soon!

Current version is 3.0.1
CP 3.1 should be release the next weeks
So CP 3.2 should be there is about 4 month (Kafka follows a time base
release cycle of 4 month and CP usually aligns with Kafka releases)

No problem. Asking questions is the purpose of mailing lists. :)
The issue will be fixed in next version of examples branch.
Examples branch is build with CP dependency and not with Kafka
dependency. CP-3.2 is not available yet; only Kafka 0.10.1.0.
Nevertheless, they should work with Kafka dependency, too. I never
tried it, but you should give it a shot...
But you should use example master branch because of API changes from
0.10.0.x to 0.10.1 (and thus, changing CP-3.1 to 0.10.1.0 will not be
compatible and not compile, while changing CP-3.2-SNAPSHOT to 0.10.1.0
should work -- hopefully ;) )

So this issue I am seeing is fixed in the next version of example branch?
Can I change my pom to point it the higher version of Kafka if that is the
issue? Or do I need to wait until new branch is made available? Sorry lot
of questions :)

The branch is 0.10.0.1 and not 0.10.1.0 (sorry for so many zeros and
ones -- super easy to mix up)
However, examples master branch uses CP-3.1-SNAPSHOT (ie, Kafka
0.10.1.0) -- there will be a 0.10.1 examples branch, after CP-3.1 was

I just now cloned this repo. It seems to be using 10.1
https://github.com/confluentinc/examples and running examples in
https://github.com/confluentinc/examples/tree/kafka-0.10.0.1-cp-3.0.1/kafka-streams

You can build librocksdbjni locally to fix it.
I did that in my case.
It is bit tricky and you need MS visual studio 15.
I suggest use the following link:
http://mail-archives.apache.org/mod_mbox/kafka-users/201608.mbox/%3CCAHoiPjweo-xSj3TiodcDVf4wNnnJ8u6PcwWDPF7LT5ps%2BxQ3eA%40mail.gmail.com%3E
Few point to remember
1. download cmake for windows
2. make sure to checkout 4.8.fb branch
3. make sure to merge this PR to you local branch
https://github.com/facebook/rocksdb/pull/1223/files
Follow the instructions in the mail and this
https://github.com/facebook/rocksdb/blob/v4.8/CMakeLists.txt
You are good to go. I suggest kafka binary to include this dll in future
releases.
Thanks
Sachin

I suspect you are running Kafka 0.10.0.x on Windows? If so, this is a
known issue that is fixed in Kafka 0.10.1 that was just released today.
Also: which examples are you referring to? And, to confirm: which git
branch / Kafka version / OS in case my guess above was wrong.
