Clara Xiong updated HBASE-26177:
--------------------------------
Description:
At times we want a one-time run for balancer with specific aggressive configs
such as recovering from a failure of 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.
