Subject [jira] [Commented] (HADOOP-13003) Add support for pushing metrics to OpenTSDB with Http
Date Tue, 05 Apr 2016 13:19:25 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15226231#comment-15226231

Mathias Herberts commented on HADOOP-13003:
-------------------------------------------

Have an OpenTSDBSink or a sink actually pushing metrics to any other platform (Graphite, Ganglia,
InfluxDB, Warp 10, ...) means you need to restart your Hadoop cluster components when you
want to change the configuration of the platform to use. Other may disagree, but restarting
DNs (or RegionServers tomorrow if the sink is used in HBase) simply for changing a metrics
platform config is not something I want to have to do on a cluster.

Having a Sink which exposes metrics through an HTTP endpoint has the benefit of loosening
the coupling between the metrics producer (Hadoop daemons) and the placeholder for those metrics.
You can then transparently switch between any of the aforementioned platforms or even use
ones that are based on polling (PrometheusIO) without touching your Hadoop cluster.
