> Key: KYLIN-3664
> URL: https://issues.apache.org/jira/browse/KYLIN-3664
> Project: Kylin
> Issue Type: Improvement
> Components: Metrics
> Reporter: Shaofeng SHI
> 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}
