--------------------------------------------
bq. Drop changes from the patch
only helping the committer :-)
bq. Are there no default value for alerting.plugins added to the
startup.properties ?
There are defaults.
{code}
org.apache.falcon.plugin.ChainableMonitoringPlugin#ChainableMonitoringPlugin
public ChainableMonitoringPlugin() {
initializeMonitoringPlugins();
initializeAlertingPlugins();
}
private void initializeAlertingPlugins() {
String pluginClasses = StartupProperties.get().
getProperty("alerting.plugins",
DefaultMonitoringPlugin.class.getName());
try {
for (String pluginClass : pluginClasses.split(",")) {
AlertingPlugin plugin =
ReflectionUtils.getInstanceByClassName(pluginClass.trim());
alertingPlugins.add(plugin);
LOG.info("Registered Alerting Plugin {}", pluginClass);
}
} catch (FalconException e) {
alertingPlugins = Arrays.asList((AlertingPlugin) new
DefaultMonitoringPlugin());
LOG.error("Unable to initialize alerting.plugins: {}",
pluginClasses, e);
}
