> Key: HBASE-29679
> URL: https://issues.apache.org/jira/browse/HBASE-29679
> Project: HBase
> Issue Type: Improvement
> Components: Quotas
> Reporter: Charles Connell
> Priority: Minor
> Attachments: failRegionAction.alloc.html, failRegionAction.cpu.html,
> failRegionAction.wall.html
>
>
> When under heavy load, a RegionServer may need to serve a very large number
> of RpcThrottlingExceptions per second. Ideally, these should be cheap to
> send, because they are HBase's load shedding mechanism.
>
> At my company, we sometimes see that sending many RpcThrottlingExceptions
> isn't always easy. The most expensive part is generating the exception's
> stack trace, and then serializing that over the wire. This is not necessary,
> so it can be skipped to save a lot of work.
