3.11 Urika-GX CLI Commands for Managing Services
Urika-GX features a number of scripts for controlling and monitoring installed analytic applications. The
commands need to be run as root from the SMW.
urika-start
The
urika-start
command is used to start analytic services on the Urika-GX system. This command can be
used to start services on one node, a number of nodes, or on all the system nodes. To specify more than one
node, specify the node IDs separated by commas. The list of services that are started using this command
depends on the service mode (default or secure) that the system is running in. This command starts all the
running services (supported in the current service mode) if used without any options. To start a specific service,
use the
-s
or
--service
option to specify the name of that service.
Using the
urika-start
command without the
-s
option will not start the Docker or Spark Thrift Server services.
Use the
-s
option to start these services, as shown below:
urika-start -s spark_thrift
urika-start -s docker
CAUTION: Before starting the Spark History server, it is required to start the following services in the
order listed:
1. HDFS NameNode
2. HDFS DataNode
For more information, see the
urika-start(8)
man page.
