[jira] [Commented] (HIVE-17088) HS2 WebUI throws a NullPointerException when opened

["Sergio Peña (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-17088?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16086529#comment-16086529 ] 

Sergio Peña commented on HIVE-17088:
------------------------------------

Here's how to check that the WebUI is working:

Use the TestMiniHS2#testConfInSession method to run a test. First, modify the code to enable the webui, then use a loop so that the test stops there:
{noformat}
    hiveConf.setBoolVar(ConfVars.HIVE_IN_TEST, false);
    miniHS2 = new MiniHS2(hiveConf);
    miniHS2.start(new HashMap<String, String>());

    while (true) {}
{noformat}

Then call the test. Ater a few seconds, go the your browser, and type "localhost:10002". You should see the WebUI working.
