I have the following config

input {  
beats {  
'port' =\> '5044'  
}  
}  
output {  
cloudwatch {  
'region'=\> 'us-west-2'  
}  
}  
I have only one conf file in /usr/share/logstash/pipeline/

bash-4.2$ ls /usr/share/logstash/pipeline  
logstash.conf  
And only one Java process from ps -ef. Running this in a container

bash-4.2$ ps -ef  
UID PID PPID C STIME TTY TIME CMD  
logstash 1 0 0 17:33 ? 00:00:00 bash -c echo -e $CONFIG \> /usr/share/logstash/pipeline/logstash.conf && /usr/local/bin/docker-entrypoint  
logstash 5 1 6 17:33 ? 00:01:00 /bin/java -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+DisableExplicitGC -Djava.awt.headl  
logstash 62 0 0 17:38 ? 00:00:00 bash  
logstash 77 62 0 17:47 ? 00:00:00 ps -ef  
However logstash fails and gives

[2017-12-06T07:36:46,505][ERROR][logstash.pipeline] A plugin had an unrecoverable error. Will restart this plugin.
