Quick update –
Just loading the YARN page generates 15.5MB of data.
Ambari is fetching 10 requests similar to this – which each generate 1.3MB of data.
/host_components/RESOURCEMANAGER?fields=metrics/yarn/Queue/root/AppsKilled[1437320528,1437324128,15],metrics/yarn/Queue/root/AppsFailed[1437320528,1437324128,15],metrics/yarn/Queue/root/AppsSubmitted[1437320528,1437324128,15],metrics/yarn/Queue/root/AppsCompleted[1437320528,1437324128,15]&_=1437324136038
This took 2.2 minutes to load on my current 1mbps connection!
Running this 1.3MB content through gzip results in a 20kilobyte file – a 98.5% reduction in size.
(it is mostly spaces).
Any chance this could be fixed as well?
