-----------------------------------------------------------------
[~dkbiswal] I just went through manual steps of creating the table in Hive (using EMR 5.0.0), inserting data into it, and then querying using spark .. and got the exception .. steps I followed -
Step 1 -
hive> create external table referencedata.testproduct (
> productid int,
> name string,
> price double,
> itemcount int
> ) PARTITIONED BY (companyid int)
> STORED AS PARQUET
> LOCATION 's3://com.birdzi.datalake.test/testtable'
> ;
Step 2 - Insert data -
set hive.exec.dynamic.partition.mode=nonstrict
insert into referencedata.testproduct partition(companyid) values(1,"p1",10.0,10,100);
insert into referencedata.testproduct partition(companyid) values(2,"p1",12.0,12,100);
insert into referencedata.testproduct partition(companyid) values(3,"p3",13.0,12,101);
Step 3 - query using spark-shell -
val d1 = spark.sql("select * from referencedata.testproduct")
val df1 = d1.sample(false,0.5).select("companyid","productid","price").groupBy("companyid","productid").agg(avg("price").as("avgprice"))
val df2 = d1.sample(false,0.5).select("companyid","productid","itemcount").groupBy("companyid","productid").agg(avg("itemcount").as("avgitemcount"))
df1.join(df2, Seq("companyid","loyaltycardnumber")) .. throws exception -
org.apache.spark.sql.AnalysisException: using columns ['companyid,'loyaltycardnumber] can not be resolved given input columns: [companyid, productid, price, avgitemcount] ;

> Key: SPARK-17709
> URL: https://issues.apache.org/jira/browse/SPARK-17709
> Project: Spark
> Issue Type: Bug
> Affects Versions: 2.0.0
> Reporter: Ashish Shrowty
> Labels: easyfix
>
> If I try to inner-join two dataframes which originated from the same initial dataframe that was loaded using spark.sql() call, it results in an error -
> // reading from Hive .. the data is stored in Parquet format in Amazon S3
> val d1 = spark.sql("select * from <hivetable>")
> val df1 = d1.groupBy("key1","key2")
> .agg(avg("totalprice").as("avgtotalprice"))
> val df2 = d1.groupBy("key1","key2")
> .agg(avg("itemcount").as("avgqty"))
> df1.join(df2, Seq("key1","key2")) gives error -
> org.apache.spark.sql.AnalysisException: using columns ['key1,'key2] can
> not be resolved given input columns: [key1, key2, avgtotalprice, avgqty];
> If the same Dataframe is initialized via spark.read.parquet(), the above code works. This same code above worked with Spark 1.6.2
