Aaron T. Myers commented on HADOOP-8228: ---------------------------------------- This is some great cleanup, Todd. The new test/testing API look good. One question: are you positive that the ordering of the two @After methods either doesn't matter, or is guaranteed to happen in the right order? One comment: maybe use a deterministic random seed for the Random instances you're using? Or at least log the amount of time that the test is sleeping for and what it's throwing? I realize that the test won't be deterministic regardless, but it will be really tough to try to reproduce test failures caused by a particular ZK disconnect pattern or health check failure pattern if we have no idea what that pattern was. +1 once those are addressed > Auto HA: Refactor tests and add stress tests > -------------------------------------------- > > Key: HADOOP-8228 > URL: https://issues.apache.org/jira/browse/HADOOP-8228 > Project: Hadoop Common > Issue Type: Test > Components: auto-failover, ha, test > Affects Versions: Auto Failover (HDFS-3042) > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Attachments: hadoop-8228.txt, hadoop-8228.txt, hadoop-8228.txt > > > It's important that the ZKFailoverController be robust and not contain race > conditions, etc. One strategy to find potential races is to add stress tests > which exercise the code as fast as possible.
