Hi All,
As per SPARK-11001 <https://issues.apache.org/jira/browse/SPARK-11001> ,
Window functions should be supported by SQLContext. But when i try to run
SQLContext sqlContext = new SQLContext(jsc);
WindowSpec w = Window.partitionBy("assetId").orderBy("assetId");
DataFrame df_2 = df1.withColumn("row_number", row_number().over(w));
df_2.show(false);
it fails with:
Exception in thread "main" org.apache.spark.sql.AnalysisException: Could not
resolve window function 'row_number'. Note that, using window functions
currently requires a HiveContext;
This code runs fine with HiveContext.
Any idea what’s going on? Is this a known issue and is there a workaround
to make Window function work without HiveContext.
Thanks,
Saurabh
