Subject [jira] [Commented] (HDFS-9438) TestPipelinesFailover assumes Linux ifconfig
Date Wed, 25 Nov 2015 00:39:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9438?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15025833#comment-15025833

Allen Wittenauer commented on HDFS-9438:

Do we actually need whoami support?  I don't think any part of hadoop-proper actually does
that anymore, just some test cases that likely haven't been touched in a while. (Although
we should probably remove that in a follow-up)

Also: RE: ifconfig

It most definitely needs to be unqualified in order for it to work across more than just Linux.
 Additionally, any switch to ip would need to be in a Linux-specific block.

>         Environment: Solaris

> 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.
