Hi guys, I load spark-csv dependencies in %spark, but not in %sql using apache zeppelin 0.5.6 with spark 1.6.0. Everything is working fine in zeppelin 0.5.5 with spark 1.5 through
Do you have similar problems? I am loading spark csv dependencies (https://github.com/databricks/spark-csv) Using: %dep z.load("PATH/commons-csv-1.1.jar") z.load("PATH/spark-csv_2.10-1.3.0.jar") z.load("PATH/univocity-parsers-1.5.1.jar:) z.load("PATH/scala-library-2.10.5.jar") I am able to load a csv from hdfs using data frame API in spark. It is running perfect fine. %spark val df = sqlContext.read .format("com.databricks.spark.csv") .option("header", "false") // Use finrst line of all files as header .option("inferSchema", "true") // Automatically infer data types .load("hdfs://sd-6f48-7fe6:8020/tmp/people.txt") // this is a file in HDFS df.registerTempTable("people") df.show() This also work: %spark val df2=sqlContext.sql("select * from people") df2.show() But this doesn't work.... %sql select * from people java.lang.ClassNotFoundException: com.databricks.spark.csv.CsvRelation$$anonfun$1$$anonfun$2 at

org.apache.zeppelin.spark.ZeppelinContext. There are something different between spark 1.5 and spark 1.6. Spark 1.5 is using SQLContext while Spark 1.6 is HiveContext. Unfortunately, no matter true or false are set in zeppelin.spark.useHiveContext, %sql just can't find csv dependencies ... try { // Use reflection because of classname returned by queryExecution changes from // Spark <1.5.2 org.apache.spark.sql.SQLContext$QueryExecution // Spark 1.6.0> org.apache.spark.sql.hive.HiveContext$QueryExecution Object qe = df.getClass().getMethod("queryExecution").invoke(df); Object a = qe.getClass().getMethod("analyzed").invoke(qe); scala.collection.Seq seq = (scala.collection.Seq) a.getClass().getMethod("output").invoke(a); columns = (List<Attribute>) scala.collection.JavaConverters.seqAsJavaListConverter(seq) .asJava(); } catch (NoSuchMethodException | SecurityException | IllegalAccessException | IllegalArgumentException | InvocationTargetException e) { throw new InterpreterException(e); } Yunfeng
