Appy commented on HBASE-19803: ------------------------------ yeah probably, i don't see any unit test calling it (although ITs do). In the non -test code, it's mostly main() fn in tools. But digging around more: - TestZKMainServer seems to be [handling System.exit() appropriately|https://github.com/apache/hbase/blob/master/hbase-zookeeper/src/test/java/org/apache/hadoop/hbase/zookeeper/TestZKMainServer.java#L85]. So do all other tests. Here's what method: https://stackoverflow.com/questions/309396/java-how-to-test-methods-that-call-system-exit - The only case where it might be wrong is, ImportTsv#createSubmittableJob calling System.exit(). TestImportTsv calls that fn multiple times. > False positive for the HBASE-Find-Flaky-Tests job > ------------------------------------------------- > > Key: HBASE-19803 > URL: https://issues.apache.org/jira/browse/HBASE-19803 > Project: HBase > Issue Type: Bug > Reporter: Duo Zhang > Priority: Major > > It reports two hangs for TestAsyncTableGetMultiThreaded, but I checked the > surefire output > https://builds.apache.org/job/HBASE-Flaky-Tests/24830/artifact/hbase-server/target/surefire-reports/org.apache.hadoop.hbase.client.TestAsyncTableGetMultiThreaded-output.txt > This one was likely to be killed in the middle of the run within 20 seconds. > https://builds.apache.org/job/HBASE-Flaky-Tests/24852/artifact/hbase-server/target/surefire-reports/org.apache.hadoop.hbase.client.TestAsyncTableGetMultiThreaded-output.txt > This one was also killed within about 1 minutes. > The test is declared as LargeTests so the time limit should be 10 minutes. It > seems that the jvm may crash during the mvn test run and then we will kill > all the running tests and then we may mark some of them as hang which leads > to the false positive. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
