这是我上传到yarn-cluster的驱动程序：
package com.baidu.spark.forhivetest
import org.apache.spark.sql._
import org.apache.spark.sql.types._
import org.apache.spark.sql.hive._
import org.apache.spark.SparkContext
object ForTest {
def main(args : Array[String]){
val sc = new SparkContext()
val sqlc = new SQLContext(sc)
val hivec = new HiveContext(sc)
hivec.sql("CREATE TABLE IF NOT EXISTS newtest (time TIMESTAMP,word STRING,current_city_name STRING,content_src_name STRING,content_name STRING)")
val schema = hivec.table("newtest").schema
println(schema)
}
在 hive 配置文件中：我设置了hive.metastore.uris和hive.metastore.warehouse.dir
在火花松比特上，我确实添加了罐子
- datanucleus-api-jdo-3.2.6.jar
- 数据核心-3.2.10.jar
- datanucleus-rdbms-3.2.9.jar
即使我添加了mysql-connector-java-5.1.38-bin.jar和spark-1.6.0-bin-hadoop2.6/lib/guava-14.0.1.jar，我仍然收到此错误！
但是当我在 ide 上运行这个火花时，它成功了！
希望有人能帮助我！ 非常感谢！
这是错误信息：

这与你的类路径有关。尽量不要堆一个胖罐子。
