> Key: HBASE-10312
> URL: https://issues.apache.org/jira/browse/HBASE-10312
> Project: HBase
> Issue Type: Bug
> Reporter: Andrew Purtell
> Assignee: Jean-Daniel Cryans
> Fix For: 0.99.0, 0.98.2, 0.96.3
>
> Attachments: HBASE-10312.java
>
>
> Steps to reproduce:
> 1. Start a cluster.
> 2. Start an ingest process.
> 3. In the HBase shell, do this:
> {noformat}
> while true do
> flush 'table'
> end
> {noformat}
> We should reject abuse via administrative requests like this.
> What happens on the cluster is the requests back up, leading to lots of these:
> {noformat}
> 2014-01-10 18:55:55,293 WARN [Priority.RpcServer.handler=2,port=8120]
> monitoring.TaskMonitor: Too many actions in action monitor! Purging some.
> {noformat}
> At this point we could lower a gate on further requests for actions until the
> backlog clears.
> Continuing, all of the regionservers will eventually die with a
> StackOverflowError of unknown origin because, stack overflow:
> {noformat}
> 2014-01-10 19:02:02,783 ERROR [Priority.RpcServer.handler=3,port=8120]
> ipc.RpcServer: Unexpected throwable object java.lang.StackOverflowError
> at java.util.ArrayList$SubList.add(ArrayList.java:965)
