Apache Pinot

Hello, i wonder if there is any guidance on troubleshoot ingestion issues. We have a table set up consuming from Kafka, but nothing is ingested. And there is  no such info/warn/error events showing up in the logs either.

Can you please check the log on both controller and server? There should be logs on why the consumption didn't start

Hi <@UDT7GFEG6>, yes I did but there was nothing. Also tried the debug table API and it shows the table status is healthy…

Can you also confirm that events are already pushed to Kafka?

It turned out the default `conf/log4j2.xml` didn’t work for us. After fixing it, we could see events being logged. With respect to the specific issue, it seems the consumption stopped right after it started.

The “info” message is like
&gt; Instance s&lt;ins_name&gt; stopped consuming segment &lt;seg_name&gt; at offset &lt;offset&gt;, …, reason: java.lang.RuntimeException
we did check the message at that specific offset but didn’t find anything wrong about it. <@UDT7GFEG6> Is there a way to get the details of this `RuntimeException`?

You should be able to find some `WARN` and `ERROR` logs explaining the exception

Didn’t see any around this info message. Any idea?

Never mind. I’ve found them. Thanks so much for your help <@UDT7GFEG6>!
