I am using logstash 1.5.5. I am using "sed" command to replace ELASTICSEARCH\_HOST variable in my logstash.conf file. But when I start logstash with such a conf file, I see that logstash cannot talk to Elasticsearch. Below is the exception (which doesn't happen when I hardcode elasticsearch host name in my .conf file)

WARNING: [logstash-logstash-1-1hghb-9-12028] failed to send ping to [[#zen\_unicast\_1#][logstash-1-1hghb][inet[elasticsearch/172.30.252.250:9200]]]

What am I doing wrong? Any help?
