Why can't I output a file (2.txt) from the input file(test.json)?  
When I execute the instruction below , I did't see any oupput in cmd.  
However, I can see the output by stdin and that record to 2.txt successfully.

/bin/pipeline\_file.config

> stdin{}

> file {

D:/test.json

> {"name" : "test"}

instruction on command line

> logstash -f pipeline\_file.config
