Erik O'Shaughnessy commented on SPARK-17944:
--------------------------------------------
AFAIK, check-hostname is a Solaris specific script written to provide a fully
qualified host name to sendmail.
I am fairly certain that before SPARK-16962 there were no Apache Spark
installations on Solaris SPARC platforms external to Oracle. My management
assures me that there is significant interest in having Apache Spark work
"out-of-the-box" on Solaris SPARC, thus my (admittedly recent) participation in
Apache Spark.
As far as your second question, whether "we know it otherwise works" on
Solaris, the only evidence I can offer is the paucity of issues raised as a
consequence of Oracle running Apache Spark on Solaris; SPARK-13776 which
tickled a Jetty bug and SPARK-16962 which addresses unaligned memory accesses.
The only other major problem we have encountered is with an Apache Spark
dependency, snappy-java, that does not support 64-bit Solaris SPARC (yet). We
have patches in-house which are under legal review.
I'll be happy to write a {{sbin/spark-funcs.sh}} so we have something concrete
to discuss.

> 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]
> starting org.apache.spark.deploy.master.Master, logging to
> /home/eoshaugh/local/spark/logs/spark-eoshaugh-org.apache.spark.deploy.master.Master-1-m7-16-002-ld1.out
> failed to launch org.apache.spark.deploy.master.Master:
> --properties-file FILE Path to a custom Spark properties file.
> Default is conf/spark-defaults.conf.
> full log in
> /home/eoshaugh/local/spark/logs/spark-eoshaugh-org.apache.spark.deploy.master.Master-1-m7-16-002-ld1.out
> {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.
