Configure ulimit using Pluggable Authentication Modules using the Command Line

Follow these command-line instructions to configure ulimit using Pluggable Authentication Modules on systems that do not use Cloudera Manager.

If you are using ulimit, you must make the following configuration changes:
  1. In the /etc/security/limits.conf file, add the following lines, adjusting the values as appropriate. This assumes that your HDFS user is called hdfs and your HBase user is called hbase.
    hdfs  -       nofile  32768
    hdfs  -       nproc   2048
    hbase -       nofile  32768
    hbase -       nproc   2048
  2. To apply the changes in /etc/security/limits.conf on Ubuntu and Debian systems, add the following line in the /etc/pam.d/common-session file:
    session required
