示例1: emitNewPartitionBatch

import storm.trident.topology.TransactionAttempt; //导入依赖的package包/类
private Map emitNewPartitionBatch(TransactionAttempt attempt, TridentCollector collector, Partition partition, Map lastMeta) {
    try {
        return failFastEmitNewPartitionBatch(attempt, collector, partition, lastMeta);
    } catch (FailedFetchException e) {
        e.printStackTrace();
    }

    Map ret = new HashMap();

    if (lastMeta != null && partition != null) {
        ret.put("offset", lastMeta.get("nextOffset"));
        ret.put("nextOffset", lastMeta.get("nextOffset"));
        ret.put("partition", partition.partition);
        ret.put("broker", ImmutableMap.of("host", partition.host.host, "port", partition.host.port));

    // exist for this processor. Only want the global one to do anything
