> Ambari's App Timeline Web UI Alert tries make http heavy call
> timelineserver:httpPort which can also cause OOM
> Hit this issue while testing ATS v1.5 on 32 node cluster under load was going
> OOM, we discovered there are instance where <ATSHost:webPort> is being hit.
> Looks like Ambari's App Timeline Web UI alerting system is trying call it
> As from Ambari Alerts we can see error like "Connection failed to
> http://ATS_HOST:8188 (timed out)"
> Now If we try hit http://<ATSHost>:<webappPort>, by default It load
> http://<ATSHost>:<webappPort>/applicationhistory
> e.g. Accessing http://ATS_HOST:8188 will try to access
> http:/ATS_HOST:8188/applicationhistory page.
> If cluster has AHS/GHS enabled (under ATS), then this call result heavy html
> containing large of application.
> We can make alert to access some lightweight call like:
> http://<ATSHost>:<webappPort>/applicationhistory/about, or
> http://<ATSHost>:<webappPort>/ws/v1/timeline
> e.g. http://ATS_HOST:8188/applicationhistory/about
> or
> http://ATS_HOST:8188/ws/v1/timeline
