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

>                 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

> {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.
