Allocating Memory for the File System Service
Describes how Warden allocates memory for the file system service.
By default, Warden adds up the total memory consumed by all services and the OS, and then
allocates 85% of the remainder to the file system. If you do not
intend to use HPE Ezmeral Data Fabric Database, you can set the
-noDB
option in configure.sh
to specify that 20% of
the memory available should be allocated to the file system
service. Allocating more memory to the file system improves
performance due to greater data caching. Data caching is especially vital when your main
constraint is disk I/O. For the parameters that you can configure to give Warden more
memory, see Allocating Memory for the OS, file system, and Hadoop Services.
