type =\> "Employeeaddr"  
start\_position =\> "beginning"  
}  
}

filter  
{  
if[path]=~"Employeeaddr" {  
csv  
{  
columns =\> ["EMPID","Employeename","country"]  
separator =\> ","  
}  
}  
}

output  
{  
if[type]=~"Employeeaddr"{  
elasticsearch {  
host =\> "localhost:9200"

Don't worry about that message. See [Suppress signal HUP warnings on startup · Issue #5239 · elastic/logstash · GitHub](https://github.com/elastic/logstash/issues/5239).

Unrelated to any problems you might have but I thought I'd mention it:

> if[path]=~"Employeeaddr" {

Make this:

```
if [path] =~ /Employeeaddr/ {

```

I am attaching my Conf file for this above error.

input{

file {  
path =\> "C:\Dillip\Logging\flogs\_1.csv"  
type =\> "flogs"  
start\_position =\> "beginning"  
}  
}

filter{

if[path]=~"flogs" {  
csv{

```
columns => ["RepositoryName","StatementType","CIN","Date"]
    separator => ","
}

```

}  
}

output{

if[type]=~"flogs"{  
elasticsearch {  
host =\> "localhost:9200"  
action =\> "create"  
index =\> "flogs"

```
}

```

}

stdout{codec=\>rubydebug}  
}

Could you pls look at the log file and help me where is the error..

`host` was renamed to `hosts` in Logstash 2.0.

This message is not fatal to Logstash. If you are having configuration errors, they are not what is generating these messages. The HUP message is actually from [JRuby](https://github.com/jruby/jruby/blob/915993886ae6663586d893b7d237f750068aceb5/core/src/main/ruby/jruby/kernel/signal.rb#L35).
