Adjusting NFS Memory Settings
The memory allocated to each MapR service is specified in the
/opt/mapr/conf/warden.conf
file, which MapR
automatically configures based on the physical memory available on
the node. You can adjust the minimum and maximum memory used for
NFS, as well as the percentage of the heap that it tries to use, by
setting the percent
, max
, and
min
parameters in the warden.conf
file on
each NFS node. Example:
...
service.command.nfs.heapsize.percent=3
service.command.nfs.heapsize.max=1000
service.command.nfs.heapsize.min=64
...
The percentages need not add up to 100; in fact, you can use
less than the full heap by setting the
heapsize.percent
parameters for all services to add up
to less than 100% of the heap size. In general, you should not need
to adjust the memory settings for individual services, unless you
see specific memory-related problems occurring.
