disable core dumps. spark\yarn

[#1]

how i can disable all cores generated by applications? 
we are based on spark\yarn

[#2]

@ilia987 In the service's configuration tab you should be able to see the Enable Core Dump property. You just have to uncheck and restart services if needed.

@ilia987 Are you using Ambari to monitor the cluster? If yes you can refer this :

https://docs.microsoft.com/en-us/azure/hdinsight/hdinsight-hadoop-collect-debug-heap-dump-linux

If you are using Cloudera Manager then you can also goto CM > Service > Configuration tab.

we are using ambari, but it is not what i wanted.
our hosts are ubuntu 18.04.
i tried the following:

• set ulimit -c 0,
• set disable core dump via code for our application:

#include <sys/types.h>
#include <sys/time.h>
#include <sys/resource.h>
   
void spc_limit_core(void) {
  struct rlimit rlim;
   
  rlim.rlim_cur = rlim.rlim_max = 0;
  setrlimit(RLIMIT_CORE, &rlim);
}​

• but when there is an error,( out of memory) an assert is generated and then a coredump,
