-----------------------------
Summary: TestSimpleRpcScheduler#testCoDelScheduling is broke
Key: HBASE-16743
URL: https://issues.apache.org/jira/browse/HBASE-16743
Project: HBase
Issue Type: Bug
Components: rpc
Reporter: stack
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
