-------------------------------
Summary: Log multi-* requests for more than threshold number of
rows
Key: HBASE-18023
URL: https://issues.apache.org/jira/browse/HBASE-18023
Project: HBase
Issue Type: New Feature
Components: regionserver
Reporter: Clay B.
Priority: Minor
Today, if a user happens to do something like a large multi-put, they can get
through request throttling (e.g. it is one request) but still crash a region
server with a garbage storm. We have seen regionservers hit this issue and it
is silent and deadly. The RS will report nothing more than a mysterious garbage
collection and exit out.
Ideally, we could report a large multi-* request before starting it, in case it
happens to be deadly. Knowing the client, user and how many rows are affected
would be a good start to tracking down painful users.
