我正在尝试访问配置单元中的视图,出现以下异常:

Getting log thread is interrupted, since query is done!
Error: Error while processing statement: FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask (state=08S01,code=2)

这是我的配置单元查询:

select * from sample_view;

我在$hive\u home/bin/hive中添加了spark\u home/jars路径,如下所示:

for f in ${SPARK_HOME}/jars/*.jar; do
     CLASSPATH=${CLASSPATH}:$f;
done

我试过了, hive.execution.engine 和斯帕克先生一样,但运气不好。

当我看到这是因为几个原因,它可以是一个红鲱鱼错误,批多个一起。在没有看到ddl表或executor日志的情况下,这是我能提供的最佳答案。
(1) java错误,导航到此作业示例的yarn日志并读取executor日志。如果这是因为一个相对罕见的错误,你会发现它在这里。祝你好运这会很痛苦。
(2) 后台服务器异常,请重新启动hadoop和hive元素并重新运行命令。
(3) 尝试在另一个进程中调用底层数据。这将发现数据是否与ddl不匹配或已损坏。
(4) 修复并使表失效

msck repair table <table-name>
invalidate metadata <table-name>

祝你好运。
