Zeppelin版本0.6.2
1. Export SPARK_HOME
In conf/zeppelin-env.sh, export SPARK_HOME environment variable with your Spark installation path.
You can optionally export HADOOP_CONF_DIR and SPARK_SUBMIT_OPTIONS
export SPARK_HOME=/usr/crh/4.9.2.5-1051/spark export HADOOP_CONF_DIR=/etc/hadoop/conf export JAVA_HOME=/opt/jdk1.7.0_79
这儿虽然添加了SPARK_HOME但是后面使用的时候还是找不到包。
2. Set master in Interpreter menu
After start Zeppelin, go to Interpreter menu and edit master property in your Spark interpreter setting. The value may vary depending on your Spark cluster deployment type.
spark解释器设置为yarn-client模式

Solution
把SPARK_HOME/lib目录下的所有jar包都拷到zeppelin的lib下。

val dataset = spark.sql("select knife_dish_power,penetration,knife_dish_torque,total_propulsion,knife_dish_speed_readings,propulsion_speed1 from `tbm.tbm_test` where knife_dish_power!=0 and penetration!=0")
如上sql中给表名和库名添加``。
然后又报如下错：

原因：我用的是org.apache.spark.sql.SQLContext对象spark查询hive中的数据，查询hive的数据需要org.apache.spark.sql.hive.HiveContext对象sqlContext或sqlc。
实例：
顺便记录一下spark-shell使用HiveContext：
集群环境是HDP2.3.4.0
spark版本是1.5.2
spark-shell scala> val hiveContext = new org.apache.spark.sql.hive.HiveContext(sc) scala> hiveContext.sql("show tables").collect().foreach(println) [gps_p1,false] scala> hiveContext.sql("select * from g").collect().foreach(println) [1,li] [1,li] [1,li] [1,li] [1,li]

Solution：
val conf = new SparkConf().setAppName("test").set("spark.driver.allowMultipleContexts", "true") val sc = new SparkContext(conf) val spark = new SQLContext(sc)
在上面添加set("spark.driver.allowMultipleContexts", "true")。
