Daniel Pinyol commented on SPARK-10067:
---------------------------------------
Fixed after upgrading to JDK 1.8.0._60. Probably due to
http://bugs.java.com/view_bug.do?bug_id=8077102
> Long delay (16 seconds) when running local session on offline machine
> ---------------------------------------------------------------------
>
> Key: SPARK-10067
> URL: https://issues.apache.org/jira/browse/SPARK-10067
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.4.1
> Environment: Mac 10.10.5, java 1.8.0_51 from IntelliJ 14.1
> Reporter: Daniel Pinyol
> Priority: Minor
>
> If I run this
> {code:java}
> SparkContext sc = new SparkContext("local", "test");
> {code}
> on a machine with no network, it hangs during 15 or 16 seconds during this
> point, and then it successfully resumes. Looks like the problem is when
> checking the kerberos realm (see callstack below).
> Is there anyway to avoid this annoying delay? I reviewed
> https://spark.apache.org/docs/latest/configuration.html, but couldn't find
> any solution.
