I'm running a slightly older version of Logstash 5.1.1 on Amazon Linux 2017.03 with openjdk 1.8.0_131 (because I'm also running the same version of Elasticsearch and Kibana). It is working in 2 clusters with the same hardware but on this one, it is unable to stay up. It keeps throwing this error:
[2017-05-11T21:05:28,185][ERROR][logstash.agent ] Pipeline aborted due to error {:exception=>#<NoMethodError: undefined method start_with?' for #<Array:0x31c79508>>, :backtrace=>["/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-5.4.0-java/lib/logstash/outputs/elasticsearch/http_client_builder.rb:80:insetup_ssl'", "org/jruby/RubyEnumerable.java:1459:in any?'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-5.4.0-java/lib/logstash/outputs/elasticsearch/http_client_builder.rb:80:insetup_ssl'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-5.4.0-java/lib/logstash/outputs/elasticsearch/http_client_builder.rb:33:in build'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-5.4.0-java/lib/logstash/outputs/elasticsearch.rb:196:inbuild_client'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-5.4.0-java/lib/logstash/outputs/elasticsearch/common.rb:13:in register'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator_strategies/shared.rb:8:inregister'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator.rb:37:in register'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:229:instart_workers'", "org/jruby/RubyArray.java:1613:in each'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:229:instart_workers'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:183:in run'", "/usr/share/logstash/logstash-core/lib/logstash/agent.rb:292:instart_pipeline'"]}`
So I tried downgrading the logstash-output-elasticsearch but that was clearly a red herring because I'm still getting the error it just now looks like:
[2017-05-11T21:33:34,708][ERROR][logstash.agent ] Pipeline aborted due to error {:exception=>#<NoMethodError: undefined method start_with?' for #<Array:0x571e49e>>, :backtrace=>["/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-5.1.1-java/lib/logstash/outputs/elasticsearch/http_client_builder.rb:76:insetup_ssl'", "org/jruby/RubyEnumerable.java:1459:in any?'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-5.1.1-java/lib/logstash/outputs/elasticsearch/http_client_builder.rb:76:insetup_ssl'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-5.1.1-java/lib/logstash/outputs/elasticsearch/http_client_builder.rb:29:in build'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-5.1.1-java/lib/logstash/outputs/elasticsearch.rb:188:inbuild_client'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-5.1.1-java/lib/logstash/outputs/elasticsearch/common.rb:13:in register'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator_strategies/shared.rb:8:inregister'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator.rb:37:in register'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:229:instart_workers'", "org/jruby/RubyArray.java:1613:in each'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:229:instart_workers'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:183:in run'", "/usr/share/logstash/logstash-core/lib/logstash/agent.rb:292:instart_pipeline'"]}
Any idea what is causing this error and how I can get logstash running smoothly again?
