Enclosed ./bin/avro-tools gives an Exception when you run it, since version 0.7.0

[Peter Ruijter]

Hello, 

I've noticed that since Divolte 0.7.0 the enclosed ./bin/avro-tools executable gives an exception when you run it. 

./divolte-collector-0.7.0/bin/avro-tools 

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/avro/ipc/Responder

at org.apache.avro.tool.Main.<init>(Main.java:39)

at org.apache.avro.tool.Main.main(Main.java:76)

Caused by: java.lang.ClassNotFoundException: org.apache.avro.ipc.Responder

In the previous packaged Divolte distributions, this error message does not occur at the time you try to run it. It's not a huge problem for me, but I just wanted to let you know. 

Environment:  Ubuntu 16.04.4 LTS

java version "1.8.0_171"

Java(TM) SE Runtime Environment (build 1.8.0_171-b11)

Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode) 

Also tested on OSX 10.13.4, with the same result. 

java version "1.8.0_66"

Java(TM) SE Runtime Environment (build 1.8.0_66-b17)

Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)

Kind regards,

Peter

Hi Peter,

Apologies for not responding earlier.

I think you are running into this: https://github.com/divolte/divolte-collector/issues/204. There is a fix for it, but that's not included in a release yet. It shouldn't be long before 0.9 gets released and this will be resolved.

In the meantime, if you have trouble looking into the Avro files, here's a blog that outlines how to do it with the regular tool chain: http://www.michael-noll.com/blog/2013/03/17/reading-and-writing-avro-files-from-the-command-line/

HTH,
Friso

Hi Friso,

Thanks for responding. I have indeed missed that GitHub issue, thank you for referring it to me. With the proposed fix in the issue I can move forward, but as indicated in my earlier post, I can also just use ./bin/avro-tools from a previous divolte-collector distro.
I look forward to version 0.9.

Kind regards,

Peter
