Saurabh Santhosh updated SPARK-11633:
-------------------------------------
Affects Version/s: 1.5.1
> HiveContext throws TreeNode Exception : Failed to Copy Node
> -----------------------------------------------------------
>
> Key: SPARK-11633
> URL: https://issues.apache.org/jira/browse/SPARK-11633
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.4.1, 1.5.0, 1.5.1
> Reporter: Saurabh Santhosh
> Priority: Critical
>
> h2. HiveContext#sql is throwing the following exception in a specific
> scenario :
> h2. Exception :
> Caused by: org.apache.spark.sql.catalyst.errors.package$TreeNodeException:
> Failed to copy node.
> Is otherCopyArgs specified correctly for LogicalRDD.
> Exception message: wrong number of arguments
> ctor: public org.apache.spark.sql.execution.LogicalRDD
> (scala.collection.Seq,org.apache.spark.rdd.RDD,org.apache.spark.sql.SQLContext)?
> h2. Code :
> {code:title=SparkClient.java|borderStyle=solid}
> StructField[] fields = new StructField[2];
> fields[0] = new StructField("F1", DataTypes.StringType, true,
> Metadata.empty());
> fields[1] = new StructField("F2", DataTypes.StringType, true,
> Metadata.empty());
>
> JavaRDD<Row> rdd =
> javaSparkContext.parallelize(Arrays.asList(RowFactory.create("", "", 0)));
> DataFrame df = sparkHiveContext.createDataFrame(rdd, new StructType(fields));
> sparkHiveContext.registerDataFrameAsTable(df, "t1");
> DataFrame aliasedDf = sparkHiveContext.sql("select f1, F2 as F2 from t1");
> sparkHiveContext.registerDataFrameAsTable(aliasedDf, "t2");
> sparkHiveContext.registerDataFrameAsTable(aliasedDf, "t3");
> sparkHiveContext.sql("select a.F1 from t2 a inner join t3 b on a.F2=b.F2");
> {code}
> h2. Observations :
> * if F1(exact name of field) is used instead of f1, the code works correctly.
> * If alias is not used for F2, then also code works irrespective of case of
> F1.
> * if Field F2 is not used in the final query also the code works correctly.
