Field Detail

SERVICES

static final String SERVICES

An array of the names of the service configurations that will be started by the ServicesManagerServer. For each value declared in this array, there must be a corresponding component defined within the Configuration.

There are four basic kinds of entries for this array:

jini

This value is recognized as the jini core services and an instance of JiniCoreServicesConfiguration is created from the corresponding configuration component.

QuorumPeerMain

This value is recognized as the zookeeper server and an instance of a ZookeeperServerConfiguration is created from the corresponding configuration component.

Any of DataServer, ClientServer, TransactionServer, LoadBalancer, MetadataServer.

These are the known bigdata server classes. An instance of the corresponding BigdataServiceConfiguration is created from the corresponding component. For example, DataServerConfiguration is created if the component name is DataServer.

other

Any other value is interpreted as a java service configuration. The name of the component is understood as the name of the main class to execute unless the JavaServiceConfiguration.Options.CLASS_NAME property is explicitly specified. This makes it possible to create more than one configuration of the same component. However, this only works for generic java services. The org.apache.log4j.net.SimpleSocketServer can be started in this manner. You can also use this to run the ServiceStarter and specify the NonActivatableServiceDescriptor in the component configuration.

ZOOKEEPER_DISCOVERY_TIMEOUT_NANOS

static final String ZOOKEEPER_DISCOVERY_TIMEOUT_NANOS

The time in nanoseconds that the ServicesManagerServer will wait the discovery of the zookeeper ensemble before throwing a fatal exception (default ).

The default is relatively long (a few minutes) so service managers will normally wait around long enough for zookeeper to start. However, zookeeper discovery is event driven so the services manager will only wait as long as necessary.
