Andrew Wong commented on KUDU-3154: ----------------------------------- I was able to reproduce this on an Ubuntu 14.04 container with openJDK 8. Running jstack (seeĀ [^kudu-3154_jstacks.txt] on the subprocess, I saw the following: {code:java} "policyDownloadTimer" #14 daemon prio=5 os_prio=0 tid=0x00007f71c0941000 nid=0x4c8de in Object.wait() [0x00007f716f4e2000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) - waiting on <0x00000006c0235468> (a org.apache.ranger.plugin.util.DownloadTrigger) at java.lang.Object.wait(Object.java:502) at org.apache.ranger.plugin.util.DownloadTrigger.waitForCompletion(DownloadTrigger.java:27) - locked <0x00000006c0235468> (a org.apache.ranger.plugin.util.DownloadTrigger) at org.apache.ranger.plugin.util.DownloaderTask.run(DownloaderTask.java:42) at java.util.TimerThread.mainLoop(Timer.java:555) at java.util.TimerThread.run(Timer.java:505) {code} This appears to be waiting for the [download trigger to fire|https://github.com/apache/ranger/blob/95a1aa57a96b392227a4f0aa4e7ecc396dca2261/agents-common/src/main/java/org/apache/ranger/plugin/util/PolicyRefresher.java#L214], but for some reason that isn't happening. It's true that the policy refresher in my logs doesn't successfully refresh the policy, but the trigger should still fire. > RangerClientTestBase.TestLogging sometimes fails > ------------------------------------------------ > > Key: KUDU-3154 > URL: https://issues.apache.org/jira/browse/KUDU-3154 > Project: Kudu > Issue Type: Bug > Components: ranger, test > Affects Versions: 1.13.0 > Reporter: Alexey Serbin > Priority: Major > Attachments: kudu-3154_jstacks.txt, ranger_client-test.txt, > ranger_client-test.txt.xz > > > The {{RangerClientTestBase.TestLogging}} scenario of the > {{ranger_client-test}} sometimes fails (all types of builds) with error > message like below: > {noformat} > src/kudu/ranger/ranger_client-test.cc:398: Failure > Failed > > Bad status: Timed out: timed out while in flight > > I0620 07:06:02.907177 1140 server.cc:247] Received an EOF from the > subprocess > I0620 07:06:02.910923 1137 server.cc:317] get failed, inbound queue shut > down: Aborted: > I0620 07:06:02.910964 1141 server.cc:380] outbound queue shut down: Aborted: > > I0620 07:06:02.910995 1138 server.cc:317] get failed, inbound queue shut > down: Aborted: > I0620 07:06:02.910984 1139 server.cc:317] get failed, inbound queue shut > down: Aborted: > {noformat} > The log is attached. -- This message was sent by Atlassian Jira (v8.3.4#803005)
