Shashikant Banerjee resolved RATIS-867. --------------------------------------- Fix Version/s: 0.6.0 Resolution: Fixed > TestMetaServer#testListLogs > --------------------------- > > Key: RATIS-867 > URL: https://issues.apache.org/jira/browse/RATIS-867 > Project: Ratis > Issue Type: Sub-task > Reporter: Shashikant Banerjee > Assignee: runzhiwang > Priority: Major > Fix For: 0.6.0 > > Attachments: image.png > > Time Spent: 1h > Remaining Estimate: 0h > > > 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.
