>            Priority: Major
>
> In HiveProducer.java, it uses a file named with the host name, this causing if there are multiple Kylin instances on the same machine, will have conflict when appending metrics to HDFS file:
>  
> {code:java}
> String hostName;
> try {
>     hostName = InetAddress.getLocalHost().getHostName();
> } catch (UnknownHostException e) {
>     hostName = "UNKNOWN";
> }
> CONTENT_FILE_NAME = hostName + "-part-0000";
> {code}
