Got Task Failed error

[certxg]

Tried out your 3.1.1 version of Sql4Dclient with the sample data, using the simple INSERTs. The .csv file was successfully created, and mysql duid_tasks table registered and showed the tasks. But it returned 'Task Failed' message. Wasn't able to pinpoint any type of issues. I only ran zookeeper and the overlord server, should I run the broker, coordinator and historical servers too? Any pointers will be appreciated.

Go through this blog http://druidwithsql.tumblr.com/post/108054375927/simple-insert-deleting-data-drop-table-in-druid . Let me know if you still face issues. BTW you can use trace=true command to enable debugging in the Slq4DClient. If you want to really see what happened with your task use Overlord console.

Thank you. This is the log that I got with 3.1.0 when trace=true and the error
Http org.apache.http.client.HttpResponseException: Not Found

The 3.1.1 version of client, on the other hand, gave a different type of errors, likely with json parsing issues.

Sometimes got different errors:
Http java.net.SocketTimeoutException: Read timed out.

Could be related to access/availability of those servers' listening ports...

If you followed the blog i sent you then the option should be
-op 8087
and not -op 8083.

Thank you for the quick response.

I changed to druid 0.6.154 and kafka 0.7.2 and it is working:

druid.extensions.coordinates=["io.druid.extensions:druid-kafka-seven:0.6.154"] instead of
druid.extensions.coordinates=["io.druid.extensions:druid-kafka-eight:0.6.160"]

The sql4dclient is 3.1.1.

Cool.

Thanks for the good work!
