Subject [jira] [Created] (HBASE-18023) Log multi-* requests for more than threshold number of rows
Date Wed, 10 May 2017 21:26:04 GMT

-------------------------------

             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.
