Lars Volker commented on IMPALA-8413: ------------------------------------- I think that code is well tested enough that we could just not run that test when running in a docker environment. > SystemStateInfoTest.ReadProcNetDev fails inside a Docker container > ------------------------------------------------------------------ > > Key: IMPALA-8413 > URL: https://issues.apache.org/jira/browse/IMPALA-8413 > Project: IMPALA > Issue Type: Bug > Components: Backend > Affects Versions: Impala 3.3.0 > Reporter: Laszlo Gaal > Priority: Major > > SystemStateInfoTest.ReadProcNetDev fails consistently when executed inside a > Docker container using test-with-docker.py (this is the container version > that hosts the complete minicluster inside the container). > The test seems to assume that by the time it runs, the number of transmitted > and received bytes and packets will both be nonzero (excluding the loopback > interface). However, this assumption fails inside the Docker container used > by test-with-docker.py. > I started a Docker-based run with test-with-docker.py, running only BE_TEST. > As the tests were running, I jumped into the container when about 75% of the > BE tests were already executed, and captured the contents of /proc/net/dev : > {code:java} > $ docker ps > CONTAINER ID IMAGE COMMAND CREATED > STATUS PORTS NAMES > 0e967d480e8d efd25829a079 "/mnt/base/entrypoin…" 17 minutes > ago Up 17 minutes i-20190414-111948-be-test > $ docker exec -it i-20190414-111948-be-test /bin/bash > impdev@i-20190414-111948:~/Impala$ cat /proc/net/dev > Inter-| Receive | Transmit > face |bytes packets errs drop fifo frame compressed multicast|bytes > packets errs drop fifo colls carrier compressed > lo: 232573986 353806 0 0 0 0 0 0 232573986 > 353806 0 0 0 0 0 0 > eth0: 828 10 0 0 0 0 0 0 0 > 0 0 0 0 0 0 0 > {code} > The layout is ugly, but it clearly shows that the number of transmitted > anything for {{eth0}} is still zero. > Additionally, it would be useful if the test logged the contents of > /proc/net/dev for failure cases. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
