Huaxin Gao commented on SPARK-10754: ------------------------------------ I believe that it's working as designed that the table name in registerTempTable is case sensitive. I will check if there are any doc for this. If not, I will probably add one. > table and column name are case sensitive when json Dataframe was registered > as tempTable using JavaSparkContext. > ----------------------------------------------------------------------------------------------------------------- > > Key: SPARK-10754 > URL: https://issues.apache.org/jira/browse/SPARK-10754 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 1.3.0, 1.3.1, 1.4.1 > Environment: Linux ,Hadoop Version 1.3 > Reporter: Babulal > > Create a dataframe using json data source > SparkConf conf=new > SparkConf().setMaster("spark://xyz:7077")).setAppName("Spark Tabble"); > JavaSparkContext javacontext=new JavaSparkContext(conf); > SQLContext sqlContext=new SQLContext(javacontext); > > DataFrame df = > sqlContext.jsonFile("/user/root/examples/src/main/resources/people.json"); > > df.registerTempTable("sparktable"); > > Run the Query > > sqlContext.sql("select * from sparktable").show() // this will PASs > > > sqlContext.sql("select * from sparkTable").show() /// This will FAIL > > java.lang.RuntimeException: Table Not Found: sparkTable > at scala.sys.package$.error(package.scala:27) > at > org.apache.spark.sql.catalyst.analysis.SimpleCatalog$$anonfun$1.apply(Catalog.scala:115) > at > org.apache.spark.sql.catalyst.analysis.SimpleCatalog$$anonfun$1.apply(Catalog.scala:115) > at scala.collection.MapLike$class.getOrElse(MapLike.scala:128) > at scala.collection.AbstractMap.getOrElse(Map.scala:58) > at > org.apache.spark.sql.catalyst.analysis.SimpleCatalog.lookupRelation(Catalog.scala:115) > at > org.apache.spark.sql.catalyst.analysis.Analyzer$ResolveRelations$.getTable(Analyzer.scala:233) > > > -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
