> Currently NameNode already provides RPC calls to get its last applied transaction ID
and most recent checkpoint's transaction ID. It can be helpful to provide support to enable
querying these information through JMX, so that administrators and applications like Ambari
can easily decide if a forced checkpoint by calling saveNamespace is necessary. Similarly
we can add MxBean interface for JournalNodes to query the status of journals (e.g., whether
journals are formatted or not).
