>                 Key: STORM-3131
>                 URL: https://issues.apache.org/jira/browse/STORM-3131
>             Project: Apache Storm
>          Issue Type: Improvement
>            Reporter: Ethan Li
>            Assignee: Ethan Li
>            Priority: Major
>              Labels: pull-request-available
>          Time Spent: 10m
>  Remaining Estimate: 0h

> We can have something like 
> {code:java}
>     public static String getBlobstoreHDFSPrincipal(Map conf) throws UnknownHostException {
>         String principal = (String)conf.get(Config.BLOBSTORE_HDFS_PRINCIPAL);
>         if (principal != null) {
>             principal = principal.replace("HOSTNAME", Utils.localHostname());
>         }
>         return principal;
>     }
> {code}
> So it will be easier to deploy storm. Instead of setting different principal on every node, we can have the same principal headless_user/HOSTNAME@DOMAIN
