Validate Service Connectivity

Use the commands in this section to test connectivity between the gateway host and the service, and then test connectivity between an external client to the service through the gateway.

	Tip
	If the communication between the gateway host and an internal service fails, telnet to the service port to verify that the gateway is able to access the cluster node. Use the hostname and ports you specified in the service definition.

1. At the gateway host, enter:

   Service	Enter
   WebHDFS	curl http://$webhdfs-host:50070/webhdfs/v1?op=GETHOMEDIRECTORY
   WebHCat/Templeton	curl http://$webhdfs-host:50111/templeton/v1/version
   Oozie	curl http://$oozie-host:11000/oozie/v1/admin/build-version
   HBase/Stargate	curl http://$hbase-host:17000/version
   HiveServer2	curl http://$hive-host:10001/cliservice

   Service	Displays
   WebHDFS	{"Path":"/user/gopher"}
   WebHCat/Templeton	{"supportedVersions":["v1"],"version":"v1"}
   Oozie	{"buildVersion":"4.0.0.2.1.1.0-302"}
   HBase/Stargate	rest 0.0.2 JVM: Oracle Corporation 1.7.0_51-24.45-b08 OS: Linux 3.8.0-29-generic amd64 Server:jetty/6.1.26 Jersey:1.8:
   HiveServer2

2. At the external client, enter:

   Service	Enter
   WebHDFS	curl https://$gateway-host:$gateway_port/$gateway/$cluster_name/$webhdfs_service_name/v1?op=GETHOMEDIRECTORY
   WebHCat/Templeton	curl https://$gateway-host:$gateway_port/$gateway/$cluster_name/$webhcat_service_name/v1/version
   Oozie	curl https://$gateway-host:$gateway_port/$gateway/$cluster_name/$oozie_service_name/v1/admin/build-version
   HBase/Stargate	curl http://$hbase-host:17000/version
   HiveServer2	curl https://$gateway-host:$gateway_port/$gateway/$cluster_name/$hive_service_name/cliservice

   Service	Displays
   WebHDFS	{"Path":"/user/gopher"}
   WebHCat/Templeton	{"supportedVersions":["v1"],"version":"v1"}
   Oozie	{"buildVersion":"4.0.0.2.1.1.0-302"}
