There could be number of reasons for that error, can you post the actual error for the log file?can you access the api elastic host on port 9200?

This is the log file

I am unable to see elasticsearch plugin head

[#4]

that log file does not tell much there should be some other stack trace in the log file indicating the actual error. are you running on one node? how much memory have you allocated? what else are you running on that node?

[#5]

This is the multinode setup. I have allocated 32GB RAM and 100GB HD memory. On this node metron server is working and elasticsearch master, storm, kibana, kafka these services are up and running.
