Sean Busbey commented on HBASE-14772: ------------------------------------- yeah, a UUID or some such specific to the current build would be perfect. on Jenkins at least, there's ${BUILD_ID} that we can use. > Improve zombie detector; be more discerning > ------------------------------------------- > > Key: HBASE-14772 > URL: https://issues.apache.org/jira/browse/HBASE-14772 > Project: HBase > Issue Type: Sub-task > Components: test > Reporter: stack > > Currently, any surefire process with the hbase flag is a potential zombie. > Our zombie check currently takes a reading and if it finds candidate zombies, > it waits 30 seconds and then does another reading. If a concurrent build > going on, in both cases the zombie detector will come up positive though the > adjacent test run may be making progress; i.e. the cast of surefire processes > may have changed between readings but our detector just sees presence of > hbase surefire processes. > Here is example: > {code} > Suspicious java process found - waiting 30s to see if there are just slow to > stop > There appear to be 5 zombie tests, they should have been killed by surefire > but survived > 12823 surefirebooter852180186418035480.jar -enableassertions -Dhbase.test > -Xmx2800m -XX:MaxPermSize=256m -Djava.security.egd=file:/dev/./urandom > -Djava.net.preferIPv4Stack=true -Djava.awt.headless=true > 7653 surefirebooter8579074445899448699.jar -enableassertions -Dhbase.test > -Xmx2800m -XX:MaxPermSize=256m -Djava.security.egd=file:/dev/./urandom > -Djava.net.preferIPv4Stack=true -Djava.awt.headless=true > 12614 surefirebooter136529596936417090.jar -enableassertions -Dhbase.test > -Xmx2800m -XX:MaxPermSize=256m -Djava.security.egd=file:/dev/./urandom > -Djava.net.preferIPv4Stack=true -Djava.awt.headless=true > 7836 surefirebooter3217047564606450448.jar -enableassertions -Dhbase.test > -Xmx2800m -XX:MaxPermSize=256m -Djava.security.egd=file:/dev/./urandom > -Djava.net.preferIPv4Stack=true -Djava.awt.headless=true > 13566 surefirebooter2084039411151963494.jar -enableassertions -Dhbase.test > -Xmx2800m -XX:MaxPermSize=256m -Djava.security.egd=file:/dev/./urandom > -Djava.net.preferIPv4Stack=true -Djava.awt.headless=true > ************ BEGIN zombies jstack extract > ************ END zombies jstack extract > {code} > 5 is the number of forked processes we allow when doing medium and large > tests.... so an adjacent build will always show as '5 zombies'. > Need to add discerning if list of processes changes between readings. > Can I also add a tag per build run that all forked processes pick up so I can > look at the current builds progeny only? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
