Setting Resource Limits on Ubuntu

About this task

Rather than relying on Warden to set resource limits automatically using ulimit, you can use the following procedure to set the limits manually.

Procedure

  1. Edit /etc/security/limits.conf and add a line to set the resource limits. For example, set the resource limits to 64K.
    <MAPR_USER> - nofile 64000 
    <MAPR_USER> - nproc 64000
  2. Edit /etc/pam.d/su and uncomment the following line.
    session required pam_limits.so
  3. Use ulimit to verify settings.
  4. Reboot the system.
  5. Run the following command as the MapR user (not root) at a command line: ulimit -n
