"uninitialized constant JBUNDLER_CLASSPATH" error while running logstash

[prashant-nair]

Hi,

I am newbie to most of the stuff like logstash, kafka. I have a kafka server running and have my logs pushed in to kafka but when I try to bin/logstash agent -f logstash.conf --debug I get the following error:

The error reported is:

I have kept the setup to a bare minimum with just one kafka broker. Here is my config file:

topic_id => "logstash"
reset_beginning => false
consumer_threads => 1
consumer_restart_on_error => true
consumer_restart_sleep_ms => 100
decorate_events => true
}
}
output {
kafka {
broker_list => "localhost:9092"
topic_id => "logstash"
compression_codec => "snappy"
request_required_acks => 1
codec => plain {
format => "%{message}"
}
}
}

What os are you running this on? How was logstash built, ie using the make
script manually?

I built logstash by running "make tarball" and my OS is CentOS 6.

[joekiller]

Okay this may be a bug introduced with the latest jruby kafka.

[prashant-nair]

is there any workaround? or are you going to fix this anytime soon? Appreciate your help!

[derryos]

I worked around this (note: not a ruby/jruby/kafka expert by any means) by commenting out the if clause at the top of:
vendor/bundle/jruby/1.9/gems/jruby-kafka-0.1.1-java/lib/jruby-kafka.rb

e.g.:
#if not JBUNDLER_CLASSPATH and ENV['KAFKA_PATH']
require 'jruby-kafka/loader'
#end

I got some problem.
I set jruby-kafka = 0.1.0 in logstash-kafka.gemspec.

[joekiller]

Revert to 0.1.0, as @zhaoxuan suggested, while building for now. I'll try to fix soon.

[joekiller]

Hey guys I pushed a version 0.1.2 that I think fixes the problem. Could you give it a shot?

[prashant-nair]

Thanks Joe. Its working now!! I am closing this issue now.
