This section describes the system BIOS configuration required.
Disable hyper-threading in the master servers, slave servers, and development servers.
Point
There is no guarantee that hyper-threading will improve performance. For this reason, this product optimizes parameters for Hadoop under the assumption that hyper-threading is disabled.
Refer to "Appendix C Hadoop Configuration Parameters" for information on Hadoop parameters.
Configure the system BIOS of the host machine when installing on a virtual environment.
Set the boot sequence for the slave server as follows:
Boot from the network interface used in the admin LAN (the first network interface)
Boot from DVD-ROM or CD-ROM (if a DVD-ROM or CD-ROM is connected)
Boot from storage
Note
Do not change the boot sequence even If operation is started from the managed Server and then booted from the disk.
If "UEFI" and "Legacy" are displayed when setting the boot from the network interface, select "Legacy".
Point
Settings are necessary to install other slave servers by cloning.
The boot sequence setting is not required when installing the slave server on a virtual environment.
