[jira] [Commented] (HBASE-7623) Username is not available for HConnectionManager to use in HConnectionKey

["Jimmy Xiang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-7623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13997664#comment-13997664 ] 

Jimmy Xiang commented on HBASE-7623:
------------------------------------

The error message is not about security I think. It seems that your application can't find your hbase-site.xml that should have the zookeeper setting. One thing you can try at first is to create a new configuration (HBaseConfiguration.create()), and make sure it has settings you expect.

> Sometimes, some non-IOException prevents User.getCurrent() to get a username.  It makes it impossible to create a HConnection.  We should catch all exception here:
> {noformat}
>       try {
>         User currentUser = User.getCurrent();
>         if (currentUser != null) {
>           username = currentUser.getName();
>         }
>       } catch (IOException ioe) {
>         LOG.warn("Error obtaining current user, skipping username in HConnectionKey",
>             ioe);
>       }
> {noformat}
> Not just IOException, so that client can move forward.
