[jira] [Created] (HDFS-7894) Rolling upgrade readiness is not updated in jmx until query command is issued.

Kihwal Lee created HDFS-7894:
--------------------------------

             Summary: Rolling upgrade readiness is not updated in jmx until query command is issued.
                 Key: HDFS-7894
                 URL: https://issues.apache.org/jira/browse/HDFS-7894
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Kihwal Lee
            Priority: Critical


When rolling upgrade is started and a rollback image is created/uploaded, the active NN does not update its {{rollingUpgradeInfo}} until it receives a query command via RPC. This results in inconsistent info being showing up in the web UI and its jmx page.
