问题
I encounter this problem while running an automated data processing script in spark-shell. First couple of iterations work fine, but it always sooner or later bumps into this error. I googled this issue but haven't found an exact match. Other similar issues are outside of spark context. I guess it may have something to do with JVM version, but I cannot figure out how to solve the problem.
I used 2 machines within a spark standalone cluster.

I managed to solve the problem by setting JAVA_HOME for spark to a java8 JDK. It is a quite new issue but has been spotted by the developers of spark, see here https://github.com/apache/spark/pull/22993/files/7f58ae61262d7c2f2d70c24d051c63e8830d5062.
The latest pre-compiled spark provided by the official site was released on Nov 2 and this pull request happened later. Hopefully later release would avoid this issue with java of newer version.
