When I start elasticsearch-8.2.0 version in Linux Centos8, it is giving following error:

```auto
0.000s][warning][os,container] Duplicate cpuset controllers detected. Picking /sys/fs/cgroup/cpuset, skipping /scratch/chroot/OL_70_x86_64/sys/fs/cgroup/cpuset.

Error: Could not find or load main class [0.000s][warning][os,container]
Caused by: java.lang.ClassNotFoundException: [0/000s][warning][os,container]

```

...  
I see the warning about duplicate cpuset but file system is read-only, so cannot modify anything there. I ran fine with same warning for elasticsearch-7.17.9.

Is there a workaround for this issue, so that I can use 8.2.0 ?

What do the Elasticsearch lots show?

There us no logs generated in logs folder except gc.log file which doesn't have any error message. I found a solution to this in another post which says:

```auto
This issue has been resolved. If anyone might run into this as well, the problem was identified to be multiple mounts of the /sys/fs/cgroup folder. Done both in the build and execution phase, removing it from either resolves this issue!

```

But these file systems are readonly for me. So, is there any other solution for this issue ?
