[jira] [Created] (HBASE-27367) Create admin/shell api for reloading just HMaster configs

Bryan Beaudreault created HBASE-27367:
-----------------------------------------

             Summary: Create admin/shell api for reloading just HMaster configs
                 Key: HBASE-27367
                 URL: https://issues.apache.org/jira/browse/HBASE-27367
             Project: HBase
          Issue Type: New Feature
            Reporter: Bryan Beaudreault


We have {{update_config}} and {{{}update_all_config{}}}. The former can do an individual host (RS or HMaster), the latter does all hosts in the cluster.  If you just want to reload HMaster(s) you need to go into JMX metrics to find the tag.ServerName for each HMaster, and then paste that into individual update_config calls.

We could either add a new {{update_hmaster_config}} or add an argument to the existing {{{}update_all_config 'hmaster'{}}}. Whatever way we go, we should add a corresponding method in Admin as well.
