Junegunn Choi created HBASE-29066:
-------------------------------------

             Summary: Fix NPE in rits.jsp when regions are not open
                 Key: HBASE-29066
                 URL: https://issues.apache.org/jira/browse/HBASE-29066
             Project: HBase
          Issue Type: Bug
            Reporter: Junegunn Choi
         Attachments: image-2025-01-10-12-54-23-094.png, image-2025-01-10-12-55-53-128.png

h2. Problem Description

I submitted a malformed alter command (has an incorrect configuration entry) and HBase failed to reopen any regions. This is expected, though not ideal.

But when you click the link on the master page and open the rits.jsp page, you see NPE errors.

h2. Solution

A simple null-check will do.
