Question-46: Number of physical drives per host may be a limiting factor in determining the number of container slots configured per node?

  1. True
  2. False

Answer: 1

Exp: The number of drives per node impacts the number of YARN containers configured for a node. YARN configuration and performance tuning is a complicated topic, but for I/O bound applications, the number of physical drives per host may be a limiting factor in determining the number of container slots configured per node.

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.
