INVALID_FETCH_SESSION_EPOCH - Sending LeaveGroup request to coordinator
cdenneen opened this issue · 11 comments
I've posted this on the forum (along with many other people but no responses and closed disussions):
https://discuss.elastic.co/t/kafka-invalid-fetch-session-epoch/187441
- I'd like to fully understand why this keeps happening.
- A better way to handle so after it "Leaves" it can "Rejoin"?
I've tried checking the logstash Monitoring API but I don't see anything here to correlate this plugin isn't working anymore after it "Leaves" so I am stuck arbitrarily looking through log output for LeaveGroup string in order to determine that I must restart logstash.
Even trying this:
max_poll_records => "200"
max_poll_interval_ms => "600000"
Still getting:

I also encountered the same situation.
Logstash can not consume message from kafka at all.
No workaround exists?
This seems related to this kafka bug https://issues.apache.org/jira/browse/KAFKA-8052
I created #327 to upgrade the client to 2.3.0, we'll publish it soon.
input and output kafka plugins have been released with kafka client 2.3.0:
https://github.com/logstash-plugins/logstash-input-kafka/blob/master/CHANGELOG.md#910
https://github.com/logstash-plugins/logstash-output-kafka/blob/master/CHANGELOG.md#810
@jsvd is this a client side bug only or server side? I'm guessing it's client side so upgrading logstash to use the 2.3.0 plugin with 2.1.0 server should fix the issue?
@cdenneen looking at apache/kafka#6582 seems to be the client side, so upgrading should fix it. That said I'm no kafka expert, I've just been scouring exception messages and hunting open/closed issues :D
I updated the Logstash plugins today, and I no longer see the INVALID_FETCH_SESSION_EPOCH messages on the logs, so looking good to me. But, contrary to what someone mentioned above, I was still able to consume at high rate before the update, and from what I understand from KAFKA-8052 it would just cause retries.
@voiprodrigo You are right.
I was misunderstood. Actually messages was consumed despite the session log.
I am getting the same errror.

upgraded to latest version of kafka still not working , i am not even able to establish a initial connection also
Seeing this. What was the solution?
@ashishbhumireddy , did you solve this issue? I've got the same one.
