Java 7 upgrade to 8 problem with Logstash


(Aymen Chetoui) #1

Hi all,

In my configuration, I have Logstash getting Syslog authentication in an EC2 instance (Instance 1) , and sending the to Elasticsearch/Kibana in a second EC2 instance (Instance 2).

When Java 7 installed on (Instance 1)

# java -version    
java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.14.04.1)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

Things work just fine with the following message :

# /opt/logstash/bin/logstash -f /etc/logstash/syslog-test.conf
'[DEPRECATED] use `require 'concurrent'` instead of `require 'concurrent_ruby'`
[2015-08-12 10:52:43.232]  WARN -- Concurrent: [DEPRECATED] Java 7 is deprecated, please use Java 8.
Java 7 support is only best effort, it may not work. It will be removed in next release (1.0).

But, when runnin the same Logstash conf file on another instance (Instance 3) with Java 8 installed.

# java -version
java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

It fails with the following message.

# /opt/logstash/bin/logstash -f /etc/logstash/syslog-test.conf
