############################ Service registration ########################################

# Here we use the 'register' function to create a simple registry of service names and to
# import (ie, 'source') any scripts required to configure/bootstrap each service
#
# The service contract requires the following:
#
# (1) The file "bin/services/{servicename}/bootstrap.sh" must exist
# (2) bootstrap.sh must implement the following wrapper functions...
#
# {servicename}Start       - Starts the service
# {servicename}Stop        - Stops the service
# {servicename}Status      - Displays current status of the service, including PIDs if running
# {servicename}Install     - Installs the service
# {servicename}Uninstall   - Uninstalls service, leaving binaries in place. Takes optional '--remove-binaries' flag
# {servicename}IsRunning   - Returns 0 if running, non-zero otherwise
# {servicename}IsInstalled - Returns 0 if installed, non-zero otherwise
# {servicename}Printenv    - Display current state of the service config
# {servicename}PidList     - Display all service PIDs on a single line, space-delimited

register java     # $DW_CLOUD_PLUGINS/java/bootstrap.sh
register maven    # $DW_CLOUD_PLUGINS/maven/bootstrap.sh
register hadoop   # $DW_CLOUD_PLUGINS/hadoop/bootstrap.sh
register accumulo # $DW_CLOUD_PLUGINS/accumulo/bootstrap.sh
register datawave # $DW_CLOUD_PLUGINS/datawave/bootstrap.sh

# You may add/remove lines above to affect which services are activated in your environment

# Order of registration is important, as it reflects install and startup order within global wrapper
# functions such as 'allInstall', 'allStart', etc. Likewise, 'allStop' and 'allUninstall' perform
# actions in reverse order of registration. See bin/common.sh for more info
