> Key: SPARK-13776
> URL: https://issues.apache.org/jira/browse/SPARK-13776
> Project: Spark
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 1.6.0
> Environment: Solaris 11.3, Oracle SPARC T-5 8 with 1024 hardware
> threads
> Reporter: Erik O'Shaughnessy
> Priority: Minor
>
> The Apache Spark Web UI fails to become available after starting a Spark
> master in stand-alone mode:
> $ ./sbin/start-master.sh
> The log file contains the following:
> {quote}
> cat spark-hadoop-org.apache.spark.deploy.master.Master-1-t5-8-002.out
> Spark Command: /usr/java/bin/java -cp

> I did some poking around and it seems that message is coming from Jetty and
> indicates a mismatch between Jetty's default maxThreads configuration and the
> actual number of CPUs available on the hardware (1024). I was not able to
> find a way to successfully change Jetty's configuration at run-time.
> Our work around was to disable CPUs until the WARN messages did not occur in
> the log file, which was when NCPUs = 504.
> I don't know for certain that this is isn't a known problem in Jetty from
> looking at their bug reports, but I wasn't able to locate a Jetty issue that
> described this problem.
> While not specifically an Apache Spark problem, I thought documenting it
> would at least be helpful.
