About the pullcentralconfig Script
The pullcentralconfig
script runs on each node in
the cluster. The pullcentralconfig
script is launched
automatically at specified intervals (the default interval is 300
seconds, which is five minutes). For each service listed in
/opt/mapr/roles
, the pullcentralconfig
script searches for corresponding configuration files in the
central configuration location,
/var/mapr/configuration
. If any configuration files
are found, it compares the timestamp (mtimes
) of the
files in the central configuration location to the timestamp of the
local version in /opt/mapr
. If the central
configuration version is newer, pullcentralconfig
overwrites the local version with the central configuration file.
To ensure that the newer version gets used, you need to restart
the associated service.
