Rob Young commented on KAFKA-17227:
-----------------------------------

Another option could be to override the java temp dir with 
`-Djava.io.tmpdir=/opt/kafka/tmp` which is working for me on 3.8.0, though that 
would affect anything that uses java temp dirs.


{code:java}
podman run -it --tmpfs /tmp:rw,size=787448k,mode=1777,noexec apache/kafka:3.8.0 
/bin/bash
42a211f01286:/$ cd /opt/kafka/
42a211f01286:/opt/kafka$ KAFKA_CLUSTER_ID="$(bin/kafka-storage.sh random-uuid)"
42a211f01286:/opt/kafka$ mkdir tmp
42a211f01286:/opt/kafka$ export KAFKA_OPTS="-Djava.io.tmpdir=/opt/kafka/tmp"
42a211f01286:/opt/kafka$ bin/kafka-storage.sh format -t $KAFKA_CLUSTER_ID -c 
config/kraft/server.properties
Formatting /tmp/kraft-combined-logs with metadata.version 3.8-IV0.{code}

> 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.
