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

> TestSimpleRpcScheduler#testCoDelScheduling is broke
> ---------------------------------------------------
>
> Key: HBASE-16743
> URL: https://issues.apache.org/jira/browse/HBASE-16743
> Project: HBase
> Issue Type: Bug
> Components: rpc
> Affects Versions: 1.3.0
> Reporter: stack
> Assignee: Mikhail Antonov
> Fix For: 1.3.0
>
>
> The testCoDelScheduling test is broke. Here are some notes on it. I have
> disabled it in the HBASE-15638 shading patch.
> {code}
> I don't get this test. When I time this test, the minDelay is > 2 * codel
> delay from the get go. So we are always overloaded. The test below would seem
> to complete the queuing of all the CallRunners inside the codel check
> interval. I don't think we are skipping codel checking. Second, I think this
> test has been broken since HBASE-16089 Add on FastPath for CoDel went in.
> The thread name we were looking for was the name BEFORE we updated: i.e.
> "RpcServer.CodelBQ.default.handler". But same patch changed the name of the
> codel fastpath thread to: new
> FastPathBalancedQueueRpcExecutor("CodelFPBQ.default", handlerCount,
> numCallQueues...
> Codel is hard to test. This test is going to be flakey given it all
> timer-based. Disabling for now till chat
> {code}
> FYI [~mantonov]
