找不到Apache Spark方法sun.nio.ch.DirectBuffer.cleaner()Lsun/misc/Cleaner; [英] Apache Spark method not found sun.nio.ch.DirectBuffer.cleaner()Lsun/misc/Cleaner;
问题描述
在spark-shell中运行自动数据处理脚本时遇到此问题.前几次迭代可以正常工作，但总是迟早会遇到此错误.我用谷歌搜索了这个问题，但没有找到完全匹配的结果.其他类似问题不在Spark上下文范围内.我想这可能与JVM版本有关，但我无法弄清楚如何解决该问题.
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.
我在Spark独立集群中使用了2台机器.
I used 2 machines within a spark standalone cluster.

推荐答案
我设法通过将spark的JAVA_HOME设置为java8 JDK来解决了该问题.这是一个相当新的问题，但已被Spark的开发人员发现，请参见此处 https://github.com/apache/spark/pull/22993/files/7f58ae61262d7c2f2d70c24d051c63e8830d5062 .
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.
官方网站提供的最新预编译星火已于11月2日发布，此拉取请求随后发生.希望以后的发行版可以避免使用较新版本的Java出现此问题.
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.
