Question-30: Select the correct statements with regards to filesystem and nproc.

1. Cloudera Manager automatically sets nproc configuration in /etc/security/limits.conf
2. Cloudera Manager automatically sets nproc configuration in /etc/security/limits.conf, but this configuration can be overridden by individual files in /etc/security/limits.d/
3. We need to make sure nproc limits are set sufficiently high, such as 65536 or 262144.
4. Low value of nproc can be a problem for Apache Impala

Answer:

Exp: Cloudera Manager automatically sets nproc configuration in /etc/security/limits.conf, but this configuration can be overridden by individual files in /etc/security/limits.d/. This can cause problems with Apache Impala and other components.

Make sure that the nproc limits are set sufficiently high, such as 65536 or 262144.
