Sean Owen commented on SPARK-17944:
-----------------------------------
Yes, for example `hostname` differs on OS X / Linux but the behavior of `-f`
happens to give the same desired output on both. Is `check-hostname` present
only on Solaris (or at least, does it do the right thing everywhere we think it
exists)? If so I could imagine just checking if that command exists and using
it if present.
There are 3 usages, and all could have the same treatment. That's not so bad
IMHO. A central script to switch out commands seems appealing but the
indirection non-trivially complicates the scripts. I'm not sure how far to go
to try to support Solaris, not because there's anything wrong with it, but
because a) I don't know how many Spark users are on Solaris, and b) I am not
sure we know it otherwise works, that there aren't other problems like this
> sbin/start-* scripts use of `hostname -f` fail with Solaris

> Key: SPARK-17944
> URL: https://issues.apache.org/jira/browse/SPARK-17944
> Project: Spark
> Issue Type: Bug
> Affects Versions: 2.0.1
> Environment: Solaris 10, Solaris 11
> Reporter: Erik O'Shaughnessy
> Priority: Trivial
>
> {{$SPARK_HOME/sbin/start-master.sh}} fails:
> {noformat}
> $ ./start-master.sh
> usage: hostname [[-t] system_name]
> hostname [-D]

> {noformat}
> I found SPARK-17546 which changed the invocation of hostname in
> sbin/start-master.sh, sbin/start-slaves.sh and sbin/start-mesos-dispatcher.sh
> to include the flag {{-f}}, which is not a valid command line option for the
> Solaris hostname implementation.
> As a workaround, Solaris users can substitute:
> {noformat}
> `/usr/sbin/check-hostname | awk '{print $NF}'`
> {noformat}
> Admittedly not an obvious fix, but it provides equivalent functionality.
