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

> -------------------------------------------------------------------------------
>
> Key: HBASE-17032
> URL: https://issues.apache.org/jira/browse/HBASE-17032
> Project: HBase
> Issue Type: Bug
> Components: Client
> Affects Versions: 1.3.0
> Reporter: Mikhail Antonov
> Assignee: Mikhail Antonov
> Fix For: 2.0.0, 1.3.0
>
>
> Back in HBASE-15137 we made it so that CQTBE causes preemptive fast fail
> exception on the client.
> It seems those 2 load control mechanists don't exactly align here. Server
> throws CallQueueTooBigException, CallDroppedException (from deadline
> scheduler) when it feels overloaded. Client should accept that behavior and
> retry. When servers sheds the load, and client also bails out, the load
> shedding bubbles up too high and high level impact on the client
> applications seems worse with PFFE turned on then without.
