HiveProducer write metrics less when one host running some kylin servers

Fails to write metrics to file becase file lease:

hdfs://xxxx/kday_date=2020-01-14/bigdata-kylin-shuyi3-00.gz01.diditaxi.com-part-0000 due to org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.protocol.AlreadyBeingCreatedException): Failed to APPEND_FILE /user/prod_kylin/bigdata_kylin/hive/bigdata_kylin/hive_metrics_query_prod3/kday_date=2020-01-14/bigdata-kylin-shuyi3-00.gz01.diditaxi.com-part-0000 for DFSClient_NONMAPREDUCE_-1428991477_29 on 100.69.76.32 because this file lease is currently owned by DFSClient_NONMAPREDUCE_-312505276_29 on 100.69.76.32

kylin-4026已解决这个问题。启动时加了个时间戳，然后outputstream一直不关，写一天，代替append。
由于同一台机器的进程不可能同毫秒初始化HiveProducer，所以必然不会冲突
