Operating system requirements
A collection of operating system requirements for Kafka.
SUSE Linux Enterprise Server (SLES)
Unlike CentOS, SLES limits virtual memory by default. Changing this default requires adding the following entries to the /etc/security/limits.conf file:
* hard as unlimited
* soft as unlimited
There are three settings you must configure properly for the kernel.
- File Descriptors
- You can set file descriptors in Cloudera Manager by going to and setting the required value. Cloudera recommends a configuration of 100000 or higher.
- Max Memory Map
- You must configure the maximum number of memory maps in your specific kernel settings. Cloudera recommends a configuration of 32000 or higher.
- Max Socket Buffer Size
- Set the buffer size larger than any Kafka
sendbuffers that you define.
