Http input on different pipeline breaks beats pipeline

[dris]

I have two pipelines for logstash:

• beats
• http

When I only use beats, everything works fine, data comes in as it should. However, when I turn on the http pipeline, http starts fine, but beats throws this error:
:exception=>#<LogStash::ConfigurationError: Cipher TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384 is not available>, :backtrace=>["/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-input-beats-6.0.8-java/lib/logstash/inputs/beats.rb:174:in create_server'", "/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-input-beats-6.0.8-java/lib/logstash/inputs/beats.rb:162:in register'", "/usr/share/logstash/logstash-core/lib/logstash/java_pipeline.rb:200:in block in register_plugins'", "org/jruby/RubyArray.java:1800:in each'", "/usr/share/logstash/logstash-core/lib/logstash/java_pipeline.rb:199:in register_plugins'", "/usr/share/logstash/logstash-core/lib/logstash/java_pipeline.rb:304:in start_inputs'", "/usr/share/logstash/logstash-core/lib/logstash/java_pipeline.rb:260:in start_workers'", "/usr/share/logstash/logstash-core/lib/logstash/java_pipeline.rb:154:in run'", "/usr/share/logstash/logstash-core/lib/logstash/java_pipeline.rb:109:in `block in start'"], "pipeline.sources"=>["/etc/logstash/conf.d/beats.conf"], :thread=>"#<Thread:0x6f92e866 run>"}

http doesn't use SSL. Beats does.

Okay, figured this out so posting here for posterity:

For some reason, when running both of those inputs (separate pipelines, same logstash instance), the default cypher defaults to TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384 and errors out.

For me, only beats was erroring out, so I proactively set:
cipher_suites => "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256"
as part of the input config for beats and it resolved itself without bare metal rebuilds or anything like that.

Hope it helps
