Unable to send message to Kafka Topic from outside of sandbox

shashank_naresh — Fri, 16 Sep 2022 14:33:21 GMT

Hi Cloudera Team,

I am getting issue while sending message to Kafka topic from outside of sandbox, but same application in sandbox is able to send message to Kafka topic.

Below is the screen print of these cases

In First case I am trying to send test message to my Kafka topic; that application runs without giving any error. But at cluster location topic was not showing any messages

In Second case when I ran the same application in sandbox messages were send and displayed in Kafka topic.

Could you please assist me what wrong I am doing (or what extra I have to do) to make my First case successful.

Hi @shashank_naresh

Did you test your connectivity with the sandbox from your host?, if not, you can try below commands:

ping sandbox-hdp.hortonworks.com

Also, you can test if the port is reachable by using:

telnet sandbox-hdp.hortonworks.com 6667

Expected output from telnet:

PC:~ mrodriguez$ telnet 172.25.40.164 6667 Trying 172.25.40.164... Connected to c489-xx.labs.xxxx.xxxx.com. Escape character is '^]'.

Cheers.

I got the solution - I should send messages to sandbox-hdf.hortonworks.com and see those messages in HDF rather than HDP.
