Confluent platform 3.0.1 windows scripts broked

[Ryan Worsley]

Hi guys,

I've been working against a trunk build and recently decided I needed to switch to the 3.0.1 download from the confluent site.

However, when I try to run various startup scripts I get various exceptions; 

• C:\kafka\bin\windows\../../etc/kafka/log4j.properties was unexpected at this time.

• Error: Could not find or load main class org.apache.zookeeper.server.quorum.QuorumPeerMain.

I'm probably being a dunce!  Please advise!

Best,

Ryan.

Documentation (http://docs.confluent.io/3.1.0/installation.html) states that:

Confluent does not currently support Windows. Windows users can download and use the zip and tar archives, but will have to run the jar files directly rather than use the wrapper scripts in the bin/ directory.

Ah Thank-you - I feel suitably silly for not having checked that!

In my defence, these scripts in the /bin/windows folder were working fine in a recent version.

Do you know if this is something that has been regressed?

Thanks,

Ryan.

I never had to or tried to run CP in Windows, so I wouldn't know.

Hi Ryan, 

I've been running ZK and Kafka successfully on Windows server recently. 

The error message w.r.t the main ZK class not being found makes me suspect that your packages (jars) were not compiled with the scala version that is expected by the \bin scrips by default (That is 2.10.6) 

One thing to try first is to set the following two variable to match the scala version of your jars. 

For instance if the packages were built with scala 2.11.8 you should run: 

C:\yourpath> set SCALA_VERSION=2.11.8

C:\yourpath> set SCALA_BINARY_VERSION=2.11

Then, if all the necessary packages are available you should be able to start, first ZK: 

C:\yourpath>.\bin\windows\zookeeper-server-start.bat .\config\zookeeper.properties

and then Kafka server: 

C:\yourpath>.\bin\windows\kafka-server-start.bat .\config\server.properties

Hope this helps.

I was getting same error when I placed kafka downloaded distribution in C:\Program Files (x86). Moving kafka downloaded distribution to some other drive other then c drive worked for me. find below working commands: D:\kafka_2.12-2.2.0\kafka_2.12-2.2.0>bin\windows\zookeeper-server-start.bat config/zookeeper.properties

Kafka was downloaded from it's official site: https://kafka.apache.org/quickstart

It might not be the drive, but rather the embedded space between Program and Files in the original path.
