You can use the yarn proxy: http:// <resourceManager>:8088/proxy/<application_ID>/api/v1/applications/<application_name>/executors
I have an scala application that monitor the number of executors of some spark streamings, and I had a similar problem, where I iterate over the running jobs and get the number of executors: val states = EnumSet.of( YarnApplicationState.RUNNING, YarnApplicationState.ACCEPTED) val it = yarnClient.getApplications(states).iterator() while (it.hasNext()) { val app = it.next() val strUrl = appReport.getTrackingUrl + "api/v1/applications/" + appReport.getName + "/executors" val url = new URL(strUrl) val urlCon = url.openConnection() val content = fromInputStream(urlCon.getInputStream) .getLines.mkString("\n") val j = JSON.parseFull(content) val currentExecutors = j.get.asInstanceOf[List[Map[String, String]]].filterNot(_("id") == "driver").size Regards, Ricardo On Thu, Feb 18, 2016 at 1:56 PM, alvarobrandon [via Apache Spark User List] <ml-node+s1001560n26267...@n3.nabble.com> wrote: > Hello: > > I wanted to access the REST API ( > http://spark.apache.org/docs/latest/monitoring.html#rest-api) of Spark to > monitor my jobs.
