Subject [jira] [Created] (HBASE-26177) Add support to run balancer overriding current config

-----------------------------------

             Summary: Add support to run balancer overriding current config
                 Key: HBASE-26177
                 URL: https://issues.apache.org/jira/browse/HBASE-26177
             Project: HBase
          Issue Type: Bug
          Components: Balancer
            Reporter: Clara Xiong


At times we want a one-time run for balancer with specific aggressive configs such as recovering
from a failure or half cluster. Currently some config are loaded dynamically but some don't.
And it could be error prone when we try to restore the configs.

With a dry run feature coming, we want to let user run a dry run with the overriding config
to choose the config and then run it. The implementation becomes more straightforward if we
allow overidding configs for both config and actual runs.
