configuration - Hive on Spark > Yarn 模式 > spark 配置 > 给 spark.master 赋什么值

Question

我正在尝试使用我自己的自定义 serde 来使用 HiveQL(它与纯 Hive 一起正常工作)。我按照以下说明进行操作:https://cwiki.apache.org/confluence/display/Hive/Hive+on+Spark%3A+Getting+Started

但是我对这部分很困惑:启动Spark集群(支持standalone和Spark on YARN)。根据我的理解，如果Spark以独立模式运行，我们只需要启动Spark集群。但是我打算在Yarn上运行Spark，是否需要启动Spark集群？我所做的是:我刚刚启动了 Hadoop Yarn，因为我真的不知道要为 spark.master 属性设置什么，所以我根本就没有设置它。可能由于此设置，我在运行使用我自己的 Serde 的 Hive 查询时收到错误消息:

2015-10-05 20:42:07,184 INFO  [main]: status.SparkJobMonitor (RemoteSparkJobMonitor.java:startMonitor(67)) - Job hasn't been submitted after 61s. Aborting it.

2015-10-05 20:42:07,184 ERROR [main]: status.SparkJobMonitor (SessionState.java:printError(960)) - Status: SENT

...

最后还有如下异常:

请尝试set spark.master=yarn-client;
