[jira] [Commented] (FLINK-7198) Metric Reporters report incorrect host for JobManager

["Bowen Li (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-7198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16094190#comment-16094190 ] 

Bowen Li commented on FLINK-7198:
---------------------------------

[~Zentol] I don't really understand Scala. So when {{jobmanager.rpc.address}} is not set, does {{NetUtils.unresolvedHostToNormalizedString(host)}} return {{127.0.0.0}}? 

Do you think this is a bug, or 'by design'?

>             Project: Flink
>          Issue Type: Bug
>          Components: Metrics
>    Affects Versions: 1.3.1
>         Environment: RHEL 7.3, Mesos 1.3, Datadog
>            Reporter: Robert Batts
>            Priority: Minor

> When using the Datadog Metric Reporter with a Mesos deployed Flink 1.3.1 cluster the JobManager is reported to Datadog with a tag of host:127.0.0.1. The TaskManagers report with the correct tag (i.e. host:mesos-02.place.com), so this just appears to be an issue with the way host information is gathered for Datadog.
