Spark On Yarn之指定hive-site.xml找不到metastore

先上代码：

  def main(args: Array[String]) {    val appName = "SparkApp"    val conf = new SparkConf().setAppName(appName)    val sc = new SparkContext(conf)    val hiveContext = new HiveContext(sc)    val df = hiveContext.sql("show databases")    LOG.info("count is " + df.count())    df.show()    sc.stop  }

场景一、

spark-submit  \--master yarn \--deploy-mode cluster \--class Spark spark.jar

结果如下图：

场景二、

spark-submit  \--master yarn \--deploy-mode client \--class Spark spark.jar

结果如下图：

场景三、

spark-submit  \--master yarn \--deploy-mode cluster \--files $HIVE_HOME/hive-site.xml \--class Spark spark.jar

结果报错：

解决问题：

查看 Driver的Classpath：

抱着试试的态度，在目录/usr/hdp/current/hadoop-client/conf/新建文件hive-ste.xml，并修改内容为：

  <configuration>   <property>      <name>hive.metastore.uris</name>      <value>thrift://ip:9083</value>    </property>  </configuration>

再次执行场景一，结果正常，哈哈！！！！
