Karan Mehta created HBASE-18117:
-----------------------------------

             Summary: Increase resiliency by allowing more parameters for online config change
                 Key: HBASE-18117
                 URL: https://issues.apache.org/jira/browse/HBASE-18117
             Project: HBase
          Issue Type: Improvement
            Reporter: Karan Mehta


HBASE-8544 adds the feature to change config online without having a server restart. This
JIRA is to work on new parameters for the utilizing that feature.

As [~apurtell] suggested, following are the useful and frequently changing parameters in production.

- RPC limits, timeouts, and other performance relevant settings
- Replication limits and batch sizes
- Region carrying limit
- WAL retention and cleaning parameters

I will try to make the RPC timeout parameter online as a part of this JIRA. If it seems suitable
then we can extend it to other params.
