Description

When running memcached application, noticed that the agent is not able to find the address of the AppMaster.

Data from registry:

  "internal" : [ {
    "api" : "classpath:org.apache.slider.agents.secure",
    "addressType" : "uri",
    "protocolType" : "REST",
    "addresses" : [ {
      "uri" : "https://c6403.ambari.apache.org:44863/ws/v1/slider/agents"
    } ]
  }, {
    "api" : "classpath:org.apache.slider.agents.oneway",
    "addressType" : "uri",
    "protocolType" : "REST",
    "addresses" : [ {
      "uri" : "https://c6403.ambari.apache.org:56339/ws/v1/slider/agents"
    } ]
  } ],

But the agent lookup keys seem to be missing "classpath:" in the beginning.

        if internal["api"] == "org.apache.slider.agents.secure":
          address0 = internal["addresses"][0]
          amUrl = address0["uri"]
          amHost = amUrl.split("/")[2].split(":")[0]
          amSecuredPort = amUrl.split(":")[2].split("/")[0]
        if internal["api"] == "org.apache.slider.agents.oneway":
          address0 = internal["addresses"][0]
          amUnsecureUrl = address0["uri"]
          amHost = amUnsecureUrl.split("/")[2].split(":")[0]
          amUnsecuredPort = amUnsecureUrl.split(":")[2].split("/")[0]
