> The ranger can be opened when the user enters http://localhost:6080/ in the
> browser address bar. But request policy from hadoop to ranger will failed
> after installing hdfs plugin if we set POLICY_MGR_URL equal to
> http://localhost:6080/.The error was as following:
> 2017-02-27 21:16:42,859 ERROR
> org.apache.ranger.admin.client.RangerAdminRESTClient: Error getting policies;
> service not found. secureMode=false, user=root (auth:SIMPLE), response=404,
> serviceName=hadoopdev, lastKnownVersion=4,
> lastActivationTimeInMillis=1488246663112
> 2017-02-27 21:16:42,867 ERROR org.apache.ranger.plugin.util.PolicyRefresher:
> PolicyRefresher(serviceName=hadoopdev): failed to find service. Will clean up
> local cache of policies (4)

> Reason:
> The brower will remove the last '/' character when the user enters
> http://localhost:6080/ in the browser address bar. The rest request address
> will be
> http://localhost:6080//service/plugins/policies/download/hadoopdev?lastKnownVersion=-1&lastActivationTime=0&pluginId=hdfs@VBoxNodeEng-1-hadoopdev
> when hadoop periodically requests policy from ranger. The request will fail
> because there are two '/' character after 'Http://localhost:6080' in
> http://localhost:6080//service/plugins/policies/download/hadoopdev?lastKnownVersion=-1&lastActivationTime=0&pluginId=hdfs@VBoxNodeEng-1-hadoopdev.
> The result is that we can't see the hdfs plugins in audit web UI.
> The program should be compatible with this situation like the browser.
> Scenario:
> The issue can be reoccurred after we set the value of
> ranger.plugin.hdfs.policy.rest.url to http://localhost:6080/ in
> ../hadoop/hadoop-2.7.3/etc/hadoop/ranger-hdfs-security.xml
> Test and verify:
> I carefully tested and verified the patch before commit the issue.
