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