Chris Nauroth commented on HDFS-9438:
-------------------------------------
[~alanburlison], thank you for reporting this. It won't work on Windows either.
The {{ifconfig}} call was part of a temporary debugging patch documented in
HDFS-6694. I've just commented on that issue asking if it's time to revert it.
> TestPipelinesFailover assumes Linux ifconfig
> --------------------------------------------
>
> Key: HDFS-9438
> URL: https://issues.apache.org/jira/browse/HDFS-9438
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: test
> Affects Versions: 2.7.1
> Environment: Solaris
> Reporter: Alan Burlison
> Assignee: Alan Burlison
> Priority: Minor
>
> TestPipelinesFailover.java contains the following:
> {code}
> scmd = new String[] {"ifconfig"};
> sce = new ShellCommandExecutor(scmd);
> sce.execute();
> System.out.println("'ifconfig' output:\n" + sce.getOutput());
> {code}
> That assumes the Linux ifconfig command. If the flag "-a" is added, the same
> invocation should work on both Linux and Solaris - the output is only
> displayed for debugging purposes so the fact that the output of ifconfig is
> different on Linux and Solaris shouldn't matter.
