Francisco Martinez commented on KAFKA-17227:
--------------------------------------------
[~jlprat], you are right. I don't use any kind of compression (nor Snappy not
Zstd). Kafka 3.7.0 and 3.7.1 run fine. And Kafka 3.8.0 does not start.
> Apache Kafka 3.8.0 /tmp exec permission

> Key: KAFKA-17227
> URL: https://issues.apache.org/jira/browse/KAFKA-17227
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 3.8.0, 3.7.1, 3.9.0
> Reporter: Francisco Martinez
> Assignee: Josep Prat
> Priority: Major
> Attachments: kafka_issue.png

>
> I have just downloaded and installed new Apache Kafka version 3.8.0.
> It does not work for me (version 3.7.1 works fine).
> In SLES 15 SP5, i have configured /etc/fstab to do not have exec permission
> for the /tmp partition (noexec) (as suggested by the CIS benchmark).
> Then the Kafka service does not start. Even the kafka-storage.sh script
> cannot be executed to create the Kafka storage in /tmp/kraft-combined-logs.
> The error reported (in all cases) is exception
> java.lang.UnsatisfiedLinkError: /tmp/lib/libzstd-jni-1.5.6-3.....so: failed
> to map segment from shared object. The error does not appear if i enable
> again the exec permission in /tmp (i.e. mount -o remount,exec /tmp).
> It seems that the zstd-jni-1.5.6-3.jar library is tried to be loaded (even in
> the case the compression is disabled by default in producer.properties:
> compression.type=none). Inside the jar file there is for example
> lizstd-jni-1.5.6-3.so for amd64 architecture that is used by the jar, and for
> that purpose it is copied to /tmp. But if the /tmp does not have execution
> permissions, the Apache Kafka processes don't start.
> Maybe the issue is in zstd-jni and has to be solved in zstd-jni, or maybe the
> library could be imported only when necessary (only in case the compression
> is used) to minimize the issue with zstd-jni.
> Thanks and regards.
