Hi, i am new to Logstash and while trying examples mentioned in the documentation, for learning purpose both Logstash1.5.3 and Elasticsearch 1.7.1 are on same machine. I am getting below warning and issue.

**Command used:** bin/logstash -f logstash-filter.conf  
output: '[DEPRECATED] use `require 'concurrent'` instead of `require 'concurrent_ruby'`  
[2015-08-19 05:01:22.323] WARN -- Concurrent: [DEPRECATED] Java 7 is deprecated, please use Java 8.  
Java 7 support is only best effort, it may not work. It will be removed in next release (1.0).  
Logstash startup completed

{  
"message" =\> "127.0.0.1 - - [11/Dec/2013:00:01:45 -0800] "GET /xampp/status.php HTTP/1.1" 200 3891 "[http://cadenza/xampp/navi.php](http://cadenza/xampp/navi.php)" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:25.0) Gecko/20100101 Firefox/25.0"",

}

It simply hangs after this and after 5 mins when I give Ctrl+C, I get the following messages which does not stops:

["INFLIGHT\_EVENTS\_REPORT", "2015-08-19T05:04:52-04:00", {"input\_to\_filter"=\>0, "filter\_to\_output"=\>0, "outputs"=\>[]}] {:level=\>:warn}  
Received shutdown signal, but pipeline is still waiting for in-flight events  
to be processed. Sending another ^C will force quit Logstash, but this may cause  
data loss. {:level=\>:warn}  
["INFLIGHT\_EVENTS\_REPORT", "2015-08-19T05:04:57-04:00", {"input\_to\_filter"=\>0, "filter\_to\_output"=\>0, "outputs"=\>[]}] {:level=\>:warn}

**Config file used is:**  
input { stdin { } }

filter {  
grok {  
match =\> { "message" =\> "%{COMBINEDAPACHELOG}" }  
}  
date {  
match =\> ["timestamp" , "dd/MMM/yyyy:HH:mm:ss Z"]  
}  
}

output {  
elasticsearch { host =\> localhost }  
stdout { codec =\> rubydebug }  
}

**Input is:**  
127.0.0.1 - - [11/Dec/2013:00:01:45 -0800] "GET /xampp/status.php HTTP/1.1" 200 3891 "[http://cadenza/xampp/navi.php](http://cadenza/xampp/navi.php)" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:25.0) Gecko/20100101 Firefox/25.0"

All I am doing is copy pasting the example mentioned in [https://www.elastic.co/guide/en/logstash/current/config-examples.html](https://www.elastic.co/guide/en/logstash/current/config-examples.html) . Feels bad that even i cant get this replayed.

I am sure something is not correct and I need some expert help.
