hadoop - 失败 : Execution Error, 从 org.apache.hadoop.hive.ql.exec.spark.SparkTask 返回代码 2

Question

我在跑

• apache-hive-1.2.1-bin
• hadoop-2.7.1
• spark-1.5.1-bin-hadoop2.6

我能够在 Spark 上配置配置单元，但是当我尝试执行查询时，它会给我以下错误消息。

hive> SELECT COUNT(*) AS rcount, yom From service GROUP BY yom;
Query ID = hduser_20160110105649_4c90528a-76ba-4127-8849-54f2152be817

  set hive.exec.reducers.bytes.per.reducer=<number>
In order to limit the maximum number of reducers:

  set mapreduce.job.reduces=<number>

FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.spark.SparkTask

我该如何解决这个问题？

Answer 1

我有同样的问题，但是我没有配置 yarn 因为一些作业正在运行。我不确定这是问题的解决方案。

yarn.resourcemanager.scheduler.class=org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler

你有没有像文档说的那样配置yarn？
