zeppelin中使用sql查询，报错：找不到表，如下

原因一般是代码里使用了 new SQLContext()，用这个sqlContext转化的dataFrame所注册的表不能被zeppelin内置的sqlContext找到。

解决办法：

一定要用zeppelin内置的SQLContext 来生成dataFrame

import org.apache.spark.SparkContext
import org.elasticsearch.spark._
import org.apache.spark.sql._
import org.elasticsearch.spark.sql._
val options13 = Map("es.nodes" -> "168.7.1.67,168.7.1.68,168.7.1.69", "es.port" -> "9200")
//val sqlContext = new SQLContext(sc)  不能新建SQLContext,否则后面的%sql 查询会查不到表
//这里一定要使用zeppelin内置的SQLContext，即sqlc
val df: DataFrame = sql.esDF("log4j-emobilelog/emobilelog", "?q=_exists_:oid",options13)
df.registerTempTable("emobilelog")
