No Data after Pipeline main started

I have created logstsh-order.conf and started the instance with that. I do see the logs Pipeline main started after that nothing happened.

No Error and no data logs. Please help me out what going wrong here

Please provide more details.
What version, what does your config, what does the logs show for LS?

using logstash-2.3.1.. It seems the query is not getting any results and it waiting with the message "SQL*Net message from client"

Unless you can provide details like the ones I have asked, we are unable to help

It is working now. Issue with the elastic search node set up. So all the nodes are not categorized. Hence logstash not able to ship the data
