Hi, When I start the logstash as a service, I receive the folowing error. I have set the pipeline.yml with a single entry as a conf file. at the same time when I start the logstash in commande line, it run correctly and starts to index in elasticsearch. Any help is appreciated. ``` [2018-04-06T12:54:47,962][FATAL][logstash.runner] An unexpected error occurred! {:error=># Did you mean? @@dotfile>, :backtrace=>["/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/awesome_print-1.8.0/lib/awesome_print/inspector.rb:163:in `merge_custom_defaults!'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/awesome_print-1.8.0/lib/awesome_print/inspector.rb:50:in `initialize'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/awesome_print-1.8.0/lib/awesome_print/core_ext/kernel.rb:9:in `ai'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-codec-rubydebug-3.0.5/lib/logstash/codecs/rubydebug.rb:39:in `encode_default'", "org/jruby/RubyMethod.java:115:in `call'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-codec-rubydebug-3.0.5/lib/logstash/codecs/rubydebug.rb:35:in `encode'", "/usr/share/logstash/logstash-core/lib/logstash/codecs/base.rb:50:in `block in multi_encode'", "org/jruby/RubyArray.java:1734:in `each'", "/usr/share/logstash/logstash-core/lib/logstash/codecs/base.rb:50:in `multi_encode'", "/usr/share/logstash/logstash-core/lib/logstash/outputs/base.rb:90:in `multi_receive'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator_strategies/single.rb:15:in `block in multi_receive'", "org/jruby/ext/thread/Mutex.java:148:in `synchronize'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator_strategies/single.rb:14:in `multi_receive'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator.rb:49:in `multi_receive'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:479:in `block in output_batch'", "org/jruby/RubyHash.java:1343:in `each'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:478:in `output_batch'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:430:in `worker_loop'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:385:in `block in start_workers'"]} [2018-04-06T12:54:48,048][DEBUG][logstash.agent] 2018-04-06 12:54:48 +0200: Listen loop error: java.nio.channels.ClosedSelectorException [2018-04-06T12:54:48,049][DEBUG][logstash.agent] sun.nio.ch.SelectorImpl.keys(SelectorImpl.java:68) org.jruby.util.io.SelectorPool.put(SelectorPool.java:88) org.jruby.util.io.SelectExecutor.selectEnd(SelectExecutor.java:59) org.jruby.util.io.SelectExecutor.go(SelectExecutor.java:44) org.jruby.RubyIO.select(RubyIO.java:3405) org.jruby.RubyIO$INVOKER$s$0$3$select.call(RubyIO$INVOKER$s$0$3$select.gen) org.jruby.internal.runtime.methods.JavaMethod$JavaMethodN.call(JavaMethod.java:721) org.jruby.internal.runtime.methods.DynamicMethod.call(DynamicMethod.java:200) org.jruby.runtime.callsite.CachingCallSite.cacheAndCall(CachingCallSite.java:338) org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:163) org.jruby.ir.interpreter.InterpreterEngine.processCall(InterpreterEngine.java:314) org.jruby.ir.interpreter.StartupInterpreterEngine.interpret(StartupInterpreterEngine.java:73) org.jruby.ir.interpreter.InterpreterEngine.interpret(InterpreterEngine.java:77) org.jruby.internal.runtime.methods.MixedModeIRMethod.INTERPRET_METHOD(MixedModeIRMethod.java:144) org.jruby.internal.runtime.methods.MixedModeIRMethod.call(MixedModeIRMethod.java:130) org.jruby.internal.runtime.methods.DynamicMethod.call(DynamicMethod.java:192) org.jruby.runtime.callsite.CachingCallSite.cacheAndCall(CachingCallSite.java:318) org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:131) org.jruby.ir.interpreter.InterpreterEngine.processCall(InterpreterEngine.java:339) org.jruby.ir.interpreter.StartupInterpreterEngine.interpret(StartupInterpreterEngine.java:73) org.jruby.ir.interpreter.Interpreter.INTERPRET_BLOCK(Interpreter.java:132) org.jruby.runtime.MixedModeIRBlockBody.commonYieldPath(MixedModeIRBlockBody.java:148) org.jruby.runtime.IRBlockBody.call(IRBlockBody.java:73) org.jruby.runtime.Block.call(Block.java:124) org.jruby.RubyProc.call(RubyProc.java:289) org.jruby.RubyProc.call(RubyProc.java:246) org.jruby.internal.runtime.RubyRunnable.run(RubyRunnable.java:104) java.lang.Thread.run(Thread.java:748) [2018-04-06T12:54:48,052][DEBUG][logstash.agent] 2018-04-06 12:54:48 +0200: Listen loop error: # [2018-04-06T12:54:48,052][DEBUG][logstash.agent] org/jruby/RubyIO.java:3405:in `select' /usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/puma-2.16.0-java/lib/puma/server.rb:322:in `handle_servers' /usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/puma-2.16.0-java/lib/puma/server.rb:296:in `block in run' [2018-04-06T12:54:48,052][DEBUG][logstash.agent] 2018-04-06 12:54:48 +0200: Listen loop error: # ``` ---

Upon investigation this error raised by the `awesome_print` library points to a problem with the value in the `ENV['HOME']` environment variable. It is probably not set. This will only occur if `ENV['HOME']` is not set AND the rubydebug codec is used. The awesome\_print library maintainers have fixed this in master but not released the fix yet. I have asked them to do this. That said, even if it was fixed, you might still have problems with Logstash or some plugins as the [POSIX specification](http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html) requires that it is set. ---

Hi, Thanks for replaying. Is there any temporary solution before fixing the bug? Where should I set this environment variable in my installation? Regards ---

The temporary solution is to set `HOME` in the shell that runs Logstash. Is it a service or a manual invocation? ---

Hi, That is running as a service. Could I hard code it some where ? Regards ---
