Josh Elser commented on HBASE-18023: ------------------------------------ bq. Patches for branch-1 and branch-1.3 Thanks! I've updated the fixVersion accordingly. > 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: Improvement > Components: regionserver > Reporter: Clay B. > Assignee: David Harju > Priority: Minor > Fix For: 2.0.0, 3.0.0, 1.4.0, 1.3.2 > > Attachments: HBASE-18023-branch-1.3.patch, > HBASE-18023-branch-1.patch, HBASE-18023.master.001.patch, > HBASE-18023.master.002.patch, HBASE-18023.master.003.patch, > HBASE-18023.master.004.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
