示例1: emitTsdbMap
import backtype.storm.task.OutputCollector; //導入方法依賴的package包/類
private boolean emitTsdbMap(String tsdbStreamId, String transferStreamId, OutputCollector collector,
Map<String, Long> tsdbMap, Map<String, Long> channelCountMap){
/**
* emit date in opentsdb-map to write-opentsdb-bold as a stream
*/
for (String tsdbKey : tsdbMap.keySet()){
String[] params = tsdbKey.split("#");
String channel = params[0];
String code = params[1];
long timestamp = (Long.valueOf(params[2]))*300;
Long total = channelCountMap.get(channel);
if (total == null){
logger.error("compute channel count wrong : " + channel);
continue;
}
double num = (tsdbMap.get(tsdbKey));
double ratio = num/total;
//future : separate transfer stream from tsdb stream
collector.emit(tsdbStreamId, new Values(channel, code, timestamp, num, ratio));
collector.emit(transferStreamId, new Values(channel, code, timestamp, num, ratio));
logger.debug(channel + "-" + code + ":" + num + "-" + ratio);
}
return true;
