----------------------------------------
Summary: Report CallDroppedException in exception metrics
Key: HBASE-26623
URL: https://issues.apache.org/jira/browse/HBASE-26623
Project: HBase
Issue Type: Improvement
Components: IPC/RPC, metrics, rpc
Reporter: Richard Marscher
Assignee: Richard Marscher
`CallDroppedException` can be thrown with `CallRunner.drop()` by queue
implementations that decide to drop calls to groom the RPC call backlog. The
LifoCoDel queue does this I believe and with Pluggable queue it's possible for
3rd party queue implementations to be using `drop()` for similar reasons (my
use case). It would be nice for the server to be tracking these exceptions in
metrics since otherwise you might have to do some extra lifting on the client
side.
I have a patch I will submit soon.
