[jira] [Created] (HBASE-17827) Client tools relying on AuthUtil.getAuthChore() break credential cache login

Gary Helmling created HBASE-17827:
-------------------------------------

             Summary: Client tools relying on AuthUtil.getAuthChore() break credential cache login
                 Key: HBASE-17827
                 URL: https://issues.apache.org/jira/browse/HBASE-17827
             Project: HBase
          Issue Type: Bug
          Components: canary, security
            Reporter: Gary Helmling
            Assignee: Gary Helmling


Client tools, such as Canary, which make use of keytab based logins with AuthUtil.getAuthChore() do not allow any way to continue without a keytab-based login when security is enabled.  Currently, when security is enabled and the configuration lacks {{hbase.client.keytab.file}}, these tools would fail with:

{noformat}
ERROR hbase.AuthUtil: Error while trying to perform the initial login: Running in secure mode, but config doesn't have a keytab

{noformat}

These tools should still work with the default credential-cache login, at least when a client keytab is not configured.
