Subject [jira] [Commented] (HBASE-7623) Username is not available for HConnectionManager to use in HConnectionKey
Date Sat, 06 Jul 2013 15:17:48 GMT

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

This is just a warning.  Your application should still work, if security is not enabled.

> 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.
