> The issue was observed here:
> [https://builds.apache.org/job/PreCommit-RATIS-Build/1299/testReport/org.apache.ratis.logservice.server/TestMetaServer/testListLogs/]
> {code:java}
> ava.lang.AssertionError: expected:<19> but was:<20>
> at
> org.apache.ratis.logservice.server.TestMetaServer.testJMXCount(TestMetaServer.java:339)
> at
> org.apache.ratis.logservice.server.TestMetaServer.testListLogs(TestMetaServer.java:331)
> {code}
>
> The reason is:
> 1. when create log, it will call
> [RaftClientImpl::sendRequestWithRetry|https://github.com/apache/incubator-ratis/blob/master/ratis-client/src/main/java/org/apache/ratis/client/impl/RaftClientImpl.java#L285],
> if throw TimeoutIOException, it will retry at [final RaftClientReply reply =
> sendRequest(request)|https://github.com/apache/incubator-ratis/blob/master/ratis-client/src/main/java/org/apache/ratis/client/impl/RaftClientImpl.java#L296],
> So JMXCount will increase many times at [timerContext =
> metricRegistry.timer(type.name()).time()|https://github.com/apache/incubator-ratis/blob/master/ratis-logservice/src/main/java/org/apache/ratis/logservice/server/MetaStateMachine.java#L224]
> when retry happens. Then JMXCount i.e. 20 not equal to createCount i.e. 19
> 2. The TimeoutIOException is as follows:
> {code:java}
> org.apache.ratis.protocol.TimeoutIOException: deadline exceeded after
> 2.999977899s. [buffered_nanos=1460409, remote_addr=localhost/127.0.0.1:9001]
