---------------------------------------
Summary: CallQueueTooBigException and CallDroppedException should
not be triggering PFFE
Key: HBASE-17032
URL: https://issues.apache.org/jira/browse/HBASE-17032
Project: HBase
Issue Type: Bug
Reporter: Mikhail Antonov
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.
