-----------------------------------------
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.
