Allocating Memory for Nodes
Describes how the Warden allocates memory for nodes.
When you run configure.sh
on a node, Warden allocates memory for the
operating system, mfs service
, data-fabricHadoop services, and applications using the settings
in the warden.conf
and the warden.<servicename>.conf
file.
Warden allocates memory to the following components in the following order:
- Operating system
mfs service
- Data Fabric Hadoop services
- Applications, such as YARN applications
- If the node only runs file system, NFS for the HPE Ezmeral Data Fabric, and gateway, then 85% of all memory is allocated to file system.
NOTE
In general, modify the settings in the warden files only under certain circumstances. If
you modify the values in warden.conf
or
warden.<servicename>.conf
file, you must restart Warden. Otherwise,
updated parameters will not be used to allocate resources.
